Those who trust Jesus cannot be condemned. Period. It is an impossibility. Why? Because the condemnation that Christians deserve for their sin was condemned in Jesus at Calvary. The death of Christ irreversibly condemned a Christian’s condemnation.
The apostle Paul writes:
“There is therefore now no condemnation for those who are in Christ Jesus…By sending his own Son in the likeness of sinful flesh and for sin, [God] condemned sin in the flesh”. (Romans 8:1, 3)
New Testament scholar Douglas Moo explains,
“…the condemnation of sin…consist[s] in God’s executing his judgment on sin in the atoning death of his Son. As our substitute, Christ ‘was made sin for us’ (2 Cor. 5:21) and suffered the wrath of God, the judgment of God upon that sin…In his doiong so, of course, we may say that sin’s power was broken, in the sense that Paul pictures sin as a power that holds people in its clutches and brings condemnation to them. In executing the full sentence of condemnation against sin, God’s effectively removed sin’s ability to ‘dictate terms’ for those who are ‘in Christ’ (v. 2). The condemnation that our sins deserve has been poured out on Christ, our sin-bearer; that is why ‘there is now no condemnation for those who are in Christ Jesus’ (v. 1).” [The Epistle to the Romans, 481]
