Sanctification is the will of God. For this is the will of God, your sanctification: that you abstain from sexual immorality; – 1 Thessalonians.4:3
A prayer that is according to the will of God will always receive an answer. This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us – 1 John.5:14
Therefore, one of the cheapest ways to deal with the issue of ungodliness is prayer. That sin which you have been enslaved to, take it up with God in prayer and ask the Holy Spirit to sanctify you. God hears a prayer that is in line with His will. Have a blessed day.
