What role does sanctification play in a Christian's life?

Sanctification is the process through which believers are made holy and useful for God's service, as articulated in 2 Timothy 2:21. It signifies being set apart for good works and cleansed from sin. This process is initiated by faith in Jesus Christ, who through His sacrifice, perfects those He sanctifies. The sermon stresses that sanctification is not a one-time event but an ongoing journey of growth in holiness, reflecting Christ's character. Believers are called to continually seek cleansing and to live in a way that honors God, thus becoming effective instruments for His work.
