How do we know that we are made new by Christ?

The assurance of being made new by Christ stems from the promises found in Scripture, particularly in 2 Corinthians 5:17, which declares, 'If any man be in Christ, he is a new creation; old things are passed away; behold, all things are become new.' This transformation occurs through the regenerating work of the Holy Spirit in the hearts of believers. The act of being made new signifies that God has sovereignly chosen and called us into fellowship with Him, guaranteeing that we now embody Christ's righteousness and holiness.
