How do we know putting on Christ is true?

The assurance of putting on Christ comes from the biblical doctrine of imputation and the promises made in Scripture. Romans 13:14 and Galatians 3:26-27 provide clarity on this subject, emphasizing that our union with Christ is a reality grounded in faith—not merely a theoretical concept. The apostle Paul argues that this act is facilitated by God's grace, ensuring that we do not approach God through our own merit but instead through the redemptive work of Christ. Through faith, we are declared righteous, effectively donning the metaphorical cloak of Christ's righteousness, which is further illustrated in various instances throughout the Bible, including the Genesis narrative.
