Christ was made sin, by virtue of being made flesh.
Rom.7:18(NAS)
For I know that in me, that is, in my flesh, dwelleth no good thing: for to will is present with me, but to do that which is good is not.
19 For the good which I would I do not: but the evil which I would not, that I practise.
20 But if what I would not, that I do, it is no more I that do it, but sin which dwelleth in me.
For I know that in me, that is,
in my flesh, dwelleth no good thing:

in sin did my mother conceive me.

2Cor.5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
he hath
made him to be sin for us, who knew no sin;
who knew no sin; Jesus never committed a sin.
Rom.8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
Rom.7:1-25
Gal.5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Heb.9:27 And as it is appointed unto men once to die, but after this the judgment:
28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
shall he appear
the second time without sin unto salvation.
Is.53:10 Yet it pleased Jehovah to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed*, he shall prolong his days, and the pleasure of Jehovah shall prosper in his hand.

12Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he poured out his soul unto death, and was
numbered with the transgressors: yet he bare the sin of many, and made intercession for the transgressors.

My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's
seed*, saith the LORD, from henceforth and for ever.
And another of the disciples said unto him, Lord, suffer me first to go and bury my father. But Jesus saith unto him, Follow me; and leave the dead to bury their own dead.(Matt.8:21-22)
