When one accept Jesus as Lord, God gave him the seal of Holy Spirit (Ephesians 1:13). From that moment Holy Spirit lives in Him and He lives in the Holy Spirit. After becoming New Creation (2 Corinthians 5:17) Sin no more remain his master. God says sin shall not have dominion over you, for you are not under the law, but under grace (Romans 6:14).

Prayer - Thanks Holy Spirit to dwell in Me and Help me to overcome every bad habit, so I can say more boldly that Sin is not my master.
