How do we know salvation is possible through faith in Christ?

The assurance of salvation through faith in Christ comes from understanding the core message of the gospel as presented in Scripture. According to Colossians 1:22, we are reconciled through Christ’s physical body and His death, which paid the penalty for our sins. By bearing our sins, He not only removes them from us but also presents us to God without blemish and free from accusation. This effect is not based on our worthiness, but on the sufficiency of Christ’s atonement and the grace of God. Therefore, for those who believe, salvation and reconciliation are not merely possible—they are guaranteed.
