More biblical support of Jesus admonishing us to live sinless lives, before entrance to heaven.

John 5:14 Afterward Jesus found him in the temple and said to him, “See, you are well! Sin no more, that nothing worse may happen to you.”

On this point most people look at this in the wrong way. Jesus was not saying for Mary or the blind man to go out and in their own strength try to not sin. He was in every sense of the matter speaking the power to overcome sin in their lives into existence.

The words of Jesus have creative power, they have the power to create, to recreate, and to sustain things in their paths without His direct attention.

So when Jesus said "Be ye therefore perfect, even as your Father which is in heaven is perfect." (Matthew 5:48) He was in no wise saying we should do this in our own strength, but was speaking the power to do so into existence for each of us. Our duty is not to fight against His reproof and admonishment but to submit to His counsel and authority.

They were compelled to strive with all their God-given powers to reach the measure of the stature of men and women in Christ Jesus. Daily they prayed for fresh supplies of grace, that they might reach higher and still higher toward perfection. Under the Holy Spirit’s working even the weakest, by exercising faith in God, learned to improve their entrusted powers and to become sanctified, refined, and ennobled. As in humility they submitted to the molding influence of the Holy Spirit, they received of the fullness of the Godhead and were fashioned in the likeness of the divine. {AA 49.3}

JSOT,

When James Saptenno refers to a "prerequisite for heaven," I understand he is referring to what EGW calls "our title to heaven." Of course the Bible is clear that "without sanctification no one will see the Lord."

Yes, a sinless, perfect character is a prerequisite to enter eternal life vs holiness is not a prerequisite for heaven.

Are they not the same? Holiness (without which no one can see the Father)- sinless perfect character, without which no one qualified for heaven (to see the Father).

But according to Angela, one is a prerequisite and the other one is not.

How about this?
Romans 3:24
Being justified freely by his grace through the redemption that is in Christ Jesus:
Romans 11:6
And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
Ephesians 2:8
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Romans 6:23
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

When eternal life from a gift becoming a reward and freely given based on faith is added with a prerequisite status a believer must achieve in his life which is a perfect sinless character?

Whatever labor needed to achieve a life status as you said (sinless perfect character or holiness) which is a prerequisite to enter heaven, to see the Father because it is a reward for your hard work of self denying, it is no longer a GIFT, but indeed a reward of works even though it is a joint operation works of the Spirit and your own will. And that view is not of the Bible.

That's why so many people accusing us teaching grace + work.

And on what base is there a discrimination between the thief on the cross and all other believers, as you have mentioned?

Yes, sure! Sin no more! Jesus has a solid ground to say that, otherwise he is not Jesus. But he never said that to sin no more is a prerequisite to enter heaven and live eternally.

What he said is more as an advice to any believer, for he knew that sinner under 6,000 years dominion of sin has a very strong tendency toward sin, as the sin is in them and dominated them, and for this He has paid our sins, not for us to strive for not to sin as a prerequisite to enter heaven and live eternally, but to justify sinner who believe Him. The thief on the cross is the great example.

Who gave the right to built a discrimination on what happen with the thief will not happen with us?

So, Sister EGW taught that! What can I say, as an SDA I will not object her although I disagree with that, for the Bible say different. And since she said that her writings is a lesser light to bring us to the greater light of understanding the bible, I will choose the greater light to led my way. Except I have been proven wrong.

Can a believer achieve a perfect sinless character without blemish?

According to my study, here what Paul said:

Romans 7:9 (NLT) At one time I lived without understanding the law. But when I learned the command not to covet, for instance, the power of sin came to life, 10 and I died.

He said later, Philippians 3:6
New Living Translation (NLT)
6 I was so zealous that I harshly persecuted the church. And as for righteousness, I obeyed the law without fault.

As a Pharisee he was perfect in keeping the law.

That one time he mentioned in Romans 7:9, he clarified later in Philippians 3:6. He thought he was perfect and blameless in his righteousness according to the law. But, seems not like that. Now, after knowing Christ he knew the sin in him and his imperfect righteousness.

Later on he said again:
1 Timothy 1:15
This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief (in present tense).

When he wrote this, he was nearly at the end of his life, and still he said "he is the chief of sinners."

So, logically, after knowing Jesus and reborn again as His believer, according to your ideas here, he will have no problem in reaching a sinless perfect character state, for now led by the Spirit, what his righteousness ever was, is now perfect, and fulfill the righteous demand of the law completely.

Where is the claim that with the joint operation of the Spirit and his will, he might reached a perfect sinless state without blemish? Instead he said "he is still a sinner" despite all of his own teaching regarding perfection.

Therefore I conclude, as Paul said:
Philippians 3:7 But what things were gain to me, those I counted loss for Christ. 8 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ, 9 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:

And this righteousness is a free gift:
Romans 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; 22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: 23 For all have sinned, and come short of the glory of God; 24 Being justified freely by his grace through the redemption that is in Christ Jesus:

We all come short of the glory of God, which means we never can attain a character that is his glory,i.e.: holiness, love, righteousness.

But because of that, justification is unconditional except by faith.

Justification is unconditional except by faith, and the only thing a man can stumbled upon and lost his gift of justification unto eternal life, is when he draw back from faith.

Hebrews 10:38 Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.

Even the wage of sin is death, and we can't stop sinning, but in Christ God forgave all our sins when we confess, and as long we remain in Christ by faith, we remain saved, and will not loose our life.

Romans 10:10
For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.

1 John 5:11
King James Version (KJV)
11 And this is the record, that God hath given to us eternal life, and this life is in his Son.

Thus, a perfect sinless character without blemish is a prerequisite for justification to enter heaven and live eternally, seems in contradiction with what I thought.

You wrote, "What you said is an example of those who has no faith in Christ, and live for self." I'm sorry my post led you to conclude I believe such a terrible thing. My apologies. Actually, I believe the fruit of rebirth is salvation, pardon, and "righteousness and true holiness".

Ephesians
4:22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
4:23 And be renewed in the spirit of your mind;
4:24 And that ye put on the new man, which after God is created in righteousness and true holiness.

This is where you are wrong and prove you are not sanctified. This can be corrected and do not think I am being aggressive towards you, which is not my intention, only to serve our perfect Christ Jesus.

It is possible to stop sinning as proven by Enoch and Elijah who would have never been allowed to enter heaven while still alive if what you say is correct.

"A few in every generation from Adam resisted his (Satan's) every artifice and stood forth as noble representatives of what it was in the power of man to do and to be, while Christ should co-operate with human efforts, to help man in overcoming the power of Satan. Enoch and Elijah are the correct representatives of what the race might be through faith in our Lord Jesus Christ. Satan was greatly disturbed because these noble, holy men were untainted amid the moral pollution surrounding them, perfecting righteous characters, and accounted worthy for translation to heaven. As they had stood forth in moral power, in noble uprightness, overcoming Satan’s temptations, he could not bring them under the dominion of death. He triumphed that he had power to overcome Moses with his temptations, and that he could mar his illustrious character and lead him to the sin of taking to himself glory before the people which belonged to God." {Con 26.1}

"In order to let Jesus into our hearts, we must stop sinning. {ST March 3, 1890, par. 3}

"Many bemoan the disobedience of Adam, which resulted in bringing sin, suffering, and death, into the world. Surely, such should cease to transgress. But instead of doing better themselves than Adam did, they follow a course of transgression, thereby increasing the tide of woe. But let the children of Adam, who have the example of their father before them with all its terrible results, stop sinning, instead of complaining of their father, while they themselves are doing worse than he did. {HR December 1, 1872, par. 8}

It IS possible to stop sinning. I love everyone in Christ and I do not wish to argue for arguments sake but for righteousness sake. Peace.
