For this is the will of God, your sanctification...
1 Thessalonians 4:3a ESV
As our walk and relationship with the Lord continues and deepens, our carnal desires and actions should both decrease. Simultaneously, our desire and actions regarding holiness should both increase.
This is called sanctification - becoming more like Christ or being conformed to the image of Christ.
We should earnestly seek to be sanctified. Shall the hatred of sin push us to want to be sanctified. Shall the Spirit of God pull us to want to be sanctified.
Christians should earnestly seek the will of God in their lives. Part of His will is wanting His children to be conformed to the image of Jesus Christ. Therefore, Christians should want to be sanctified and seek the Lord in prayer and in the Word to be sanctified more (more holy).
Christian, is this your heart's desire or are you feeling 'comfortable' in complacency?
