Whatever takes the place of God in your life is a false altar. Do you pretend to be worshiping God and yet you find it comfortable to tell lies, get involved in fornication and adultery? Do you have sinful friends you still relate with, comfortably? Is there anything that still pushes you to sin? These are false altars.

” In the morning when the people of the town got up, there was Baal’s altar, demolished, with the Asherah pole beside it cut down and the second bull sacrificed on the newly built altar!  Judges 6:28

It is always difficult to handle them with human strength. Ask God to help you and deliver you, you will find strength in Jesus’ name to pull down those altars.
