In Christ were united the divine and the human--the Creator and the creature. The nature of God, whose law had been transgressed, and the nature of Adam, the transgressor, meet in Jesus--the Son of God, and the Son of man. (7 SDABC 926)

M: Jesus did not have an evil heart; instead, He was incarnated with the same sinful flesh you and I inherited at birth. Yes, His sinless, divine nature recoiled from evil; nevertheless, His sinful nature clamored for sinful expression. Such clamoring do not constitute a sin, nor does it contaminate or corrupt character.

A: We have two sources of sin: Satan and the evil of our own hearts. That's according to the MB quote. If Jesus did not have an evil heart, that only leaves Him with Satan as a source of temptation. Right?

There is earnest warfare before all who would subdue the evil tendencies that strive for the mastery. {GC 489.3}

The conflict will be close between self and the grace of God. Self will strive for the mastery and will be opposed to the work of bringing the life and thoughts, the will and affections, into subjection to the will of Christ. {2T 687.3}

Every day hereditary tendencies to wrong will strive for the mastery. Every day you are to war against your objectionable traits of character, until there are left in you none of those things which need to be separated from you. Then you will think candidly and wisely how to take yourself to the Lord. You will foresee the evils which will come, unless you change by avoiding the cause which produces the effect. {VSS 304.4}

He who has determined to enter the spiritual kingdom will find that all the powers and passions of unregenerate nature, backed by the forces of the kingdom of darkness, are arrayed against him. Each day he must renew his consecration, each day do battle with evil. Old habits, hereditary tendencies to wrong, will strive for the mastery, and against these he is to be ever on guard, striving in Christ's strength for victory. {AA 476.3}

He who determines to enter the spiritual kingdom will find that all the powers and passions of an unregenerate nature, backed by the forces of the kingdom of darkness, are arrayed against him. Selfishness and pride will make a stand against anything that would show them to be sinful. We cannot, of ourselves, conquer the evil desires and habits that strive for the mastery. We cannot overcome the mighty foe who holds us in his thrall. God alone can give us the victory. He desires us to have the mastery over ourselves, our own will and ways. But He cannot work in us without our consent and co-operation. The divine Spirit works through the faculties and powers given to man. Our energies are required to co-operate with God. {MB 141.3}

The lower passions have their seat in the body and work through it. The words "flesh" or "fleshly" or "carnal lusts" embrace the lower, corrupt nature; the flesh of itself cannot act contrary to the will of God. We are commanded to crucify the flesh, with the affections and lusts. How shall we do it? Shall we inflict pain on the body? No; but put to death the temptation to sin. The corrupt thought is to be expelled. Every thought is to be brought into captivity to Jesus Christ. All animal propensities are to be subjected to the higher powers of the soul. {AH 127.2}

How can Jesus be tempted by MY evil? I did not personally tempt Him. And I certainly do not have the power to transfer my sin/evil to Him.

Those are the two sources of temptation that we read in MB. Do you believe there are other sources?

And I thought you believe that the suffering which sin brings is a direct result of the sin itself. How can MY sin cause a sinless third party to suffer?
