Once again, this poster does not address that fact Jesus could not have been "sin" and "just" at the same time. Saying the very words of scripture come from my imagination is not helpful, but reflects the reasoning of those denying scripture.
Once again this poster does not address the fact that the Bible specifically states that our Lord was made sin and that therefore he needs to think outside of hos prejudices and his limited Biblical understanding.. The Bible does not share his concerns. Peter says that God
'judges justly' immediately before explaining that He
'bore our sins.' (1 Peter 2:23-24). Paul explains that the rreason that Christ was set forth as a propitiation was that He might be
'just and the justifier of the one who believes in Jesus' Romans 3:25-26).
2 Corinthians 5:21 states that Christ was made sin
'that we might become the rrighteousness of God in Him'. First of all, who are 'we'? 'We' are
'the church of God which is in Corinth , with all the saints who are in all Achaia' (2 Corinthians 1:1) and even more importantly,
'...All who in every place call upon the name of Jesus Christ our Lord, both theirs and ours' (1 Corinthians 1:2b). So Christ was made whatever He was made,, not for everyone, but for believers only.
Secondly, What does
'in Him' mean? It means that we are not an unrelated third party; He is in us, and we in Him, indwelt by His Spirit. Our union with Christ is not physical but spiritual, but nonetheless real for al that. Our justification, our adoption and our reigning with Christ in the heavenly places are all 'in Christ.' Our guilt is imputed to Christ and His perfect righteousness to us through this union. Luther likens this to a couple who marry although one of them is deep in debt.. The other party nevertheless willingly takes that debt upon himself and settles it himself. Ephesians 5:25 uses marriage as a illustration of the costly love of Christ in which He entered into union with His people, those whom God had given Him Hebrews 2:13; John 6:39).
Does Isaiah 53:6 say the sin of the elect were laid on Jesus or the sin of all humanity? All who have gone astray refers to all humanity.

Isaiah 53:6 does not say 'all who have gone astray,' it says ,
'All we like sheep have gone astray, and the LORD has laid on Him the iniquity of us all.' We being God's elect. There was no rreason for Isaiah to have added the 'we' if he meant every single person.
Does 1 Peter 2:24 say the sins of only those saved were laid on Jesus, or that the sins of those saved were laid on Jesus without addressing those never saved?
'....Who Himself bore our sins in His own body on the tree.....' Who is Paul writing to? Those who are
'....elect according to the foreknowledge of God the Father..... etc.'
Does Isaiah 61:10 say righteousness is "credited" to believers? Nope
Yep! The robe of righteousness and the garments of salvation are given to sinners, therefore the righteousness is that of Jesus Christ credited to us, not something we stitch together of our own.
And Romans 5:19 says we were "made" righteous.
Made righteous by imputation. Romans 5:1 tells us that Christ died for the ungodly and Romans 4:5 tells us that He justifies the ungodly.
'...... Not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is ffrom God by faith' (Philippians 3:9).
