Bible never says Jesus became a sinner. A sinner is someone who commits sin. Jesus became sin for us and received the penalty of God’s wrath, but Jesus never sinned. He took on the sins of mankind without sinning Himself.
Bible never says Jesus died spiritually.
Psalm 75:
Isaiah 51:
1 John 3:5
But you know that Christ appeared to take away sins, and in Him there is no sin.
Hebrews 4:15
For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who was tempted in every way that we are, yet was without sin.
1 Peter 3:18
For Christ also suffered for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit.
Isa 53:4-6, Surely He took on our infirmities and carried our sorrows; yet we considered Him stricken by God, struck down and afflicted. But He was pierced for our transgressions, He was crushed for our iniquities; the punishment that brought us peace was upon Him, and by His stripes we are healed. We all, like sheep, have gone astray, each of us has turned to our own way; and the LORD has laid on him the iniquity of us all.
