Tearing Out the Idols in Our Hearts

Ladies,
How to recognize idols in our hearts and lives and how to repent and make Jesus Lord.
I quoted the Catholic definition of idolatry. I go to a Baptist church. But - all people who love, worship and live for Christ as Savior and Lord belong to Jesus' church. I do not agree with all of the teachings of the Catholic church as being biblical. But I do appreciate this particular definition of idolatry.
John Calvin said, "The human heart is an idol factory."
