1) Who said that the text means Christ was made to be sin at His birth? I understand it to mean He was made to be sin on the cross.
2) "Sin" is in opposition to "righteousness." If sin was physical, so would be righteousness.

In the Tuesday section of the SS lesson for next Sabbath EGW tells us why Jesus came to this world . That gives us what we need to know.

It seems as though Jesus bore the sins of the world His entire life while on earth:

That's not what I said. What I said is that you have a very small percentage of the total data related to "the life of Christ on this earth." You obviously do not comprehend the distinction. It's subtle, but significant. More algebra skill may be called for.

Given your documented history of miscomprehension, I don't know how anyone can take your statements too seriously.

I wouldn't do that with my son. I'm more likely to let the results of his own foolishness speak for itself.

But that's not what happened to Nadab and Abihu, was it? They did not die of old age.

And if you think it was Satan who stepped in to make an abrupt end to their profane sacrifice, then you and I don't agree on Satan's intentions.

If you want to know the real character of the God of the OT, then look at Jesus. If your picture does not fit Jesus, then there is something wrong with your picture.
1 Corinthians 13:1-13
1 If I speak with the tongues of men and of angels, but have not love, I am become sounding brass, or a clanging cymbal.
2 And if I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but have not love, I am nothing.
3 And if I bestow all my goods to feed the poor, and if I give my body to be burned, but have not love, it profiteth me nothing.
4 Love suffereth long, and is kind; love envieth not; love vaunteth not itself, is not puffed up,
5 doth not behave itself unseemly, seeketh not its own, is not provoked, taketh not account of evil;
6 rejoiceth not in unrighteousness, but rejoiceth with the truth;
7 beareth all things, believeth all things, hopeth all things, endureth all things.
8 Love never faileth: but whether there be prophecies, they shall be done away; whether there be tongues, they shall cease; whether there be knowledge, it shall be done away.
9 For we know in part, and we prophesy in part:
10 but when that which is perfect is come, that which is in part shall be done away.
11 When I was a child, I spake as a child, I felt as a child, I thought as a child: now that I am become a man, I have put away childish things.
12 For now we see in a mirror, darkly; but then face to face: now I know in part; but then shall I know even as also I have been known.
13 But now abideth faith, hope, love, these three; and the greatest of these is love.

Sin is an illness problem?

Was the original sin an illness problem?

Also, show me where Scripture depicts sin as an illness problem.

Hebrew parallelism:
Jeremiah 17:14 Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise.

Isaiah 53:3-5 He was despised and rejected by others; a man of suffering and acquainted with infirmity; and as one from whom others hide their faces he was despised, and we held him of no account. 4 Surely he has borne our infirmities and carried our diseases; yet we accounted him stricken, struck down by God, and afflicted. 5 But he was wounded for our transgressions, crushed for our iniquities; upon him was the punishment that made us whole, and by his bruises we are healed.

Matthew 8:17 That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.

James 5:16 Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.

Exodus 31:13 Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the LORD that doth sanctify you.

Jeremiah 31:30-33 But every one shall die for his own iniquity: every man that eats the sour grape, his teeth shall be set on edge. 31 Behold, the days come, said the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: 32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they broke, although I was an husband to them, said the LORD: 33 But this shall be the covenant that I will make with the house of Israel; After those days, said the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.

Hebrew parallelism
Psalms 103:3 Who forgiveth all thine iniquities; who healeth all thy diseases;

Revelation 22:2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.

Exodus 15:26 And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.

What happened to man right at the beginning? And not only man, but all creation?
Genesis 3:14-18
14 And the LORD God said unto the serpent, Because thou hast done this, cursed art thou above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
15 and I will put enmity between thee and the woman, and between thy seed and her seed: it shall bruise thy head, and thou shalt bruise his heel.
16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
17 And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in toil shalt thou eat of it all the days of thy life;
18 thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;

"remission of sins" - remission, Greek word, Aphesis. If you have cancer, do you want the cancer pardoned, or do you want the cancer to go into "remission"?
Matthew 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.

1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
Forgive - Greek word Aphiemi, rooted with Aphesis, to remove, remit, send away. It is something that happens in the offender, not the offended. Not our common useage of the term forgive.

Why did Jesus spend most of His time healing? Because it best represents the work of the Gospel - restoration.

What is the difference between "not much"(me) and "very little"(asygo)? I do have an engineering degree. This discussion arose around a quote in volume 8 of the testimonies, to which asygo said, He did not know that the testimonies were indeed the primary source of the quote. And if he had read the quote in context, then he would have known that what I said was indeed correct. Shall I quote the section in the primary source? What she is talking about is the life of Christ on this earth. In that other thread, I also quoted from the book, "Ministry of Healing" (Daryl - you might like to note the title). She is speaking of Christ's life as a human, on this earth. She when on to speak about Christ's revelations to His disciples, quoting John 14. These men knew the Old Testament, and a I dare say better that most of us! And they were confused about the character of God. Christ cleared up the confusion, "If you have seen Me, you have seen the Father". And John 16, "The Father love you Himself"! Yes, our view of the OT God needs to be looked at with the what we see through the glasses of the NT Christ. But as asygo says, don't trust what I say, read the evidence for your self.

1) Show me this from scripture or EGW. The fact still remains, that he bore our sins "in His body". Galatians 4:4-5 But when the fullness of the time was come, God sent forth his Son, made of a woman, made under the law, 5 To redeem them that were under the law, that we might receive the adoption of sons. Hebrews 2:17 Why in all things it behooved him to be made like to his brothers, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.

2) There is "sin" and there are "sins". "sins" is the behavior. "Sin" is the disease. Christ bore ouf "sin", but never committed any "sins", he was spotless. EGW puts it this way, "By taking upon Himself man's nature in its fallen condition, Christ did not in the least participate in its sin." Notice the word structure.
