We become what we worship. If we worship what is true we will become true. If we worship what is false, we become false as stated above. Our souls are designed for worship. As St. Augustine says, "Our hearts are restless until they rest in thee." The first two commandments deal with God's uniqueness and the prohibition against any man-made substitute. Idolatry is not just a carved image but anything we desire before God.
John Calvin, the great reformer said, “Every one of us is, even from his mother's womb, a master craftsman of idols” We can even make our image of God be an idle when our image contradicts the revelation of God’s nature found in Scripture.
Everything around us in the world we live in tempts us to idolatry. The American culture praises fame and fortune. Some TV preachers reinforce this saying God wants you to have it all! False prophets are not in short supply. The truth is found in all the words of Scripture. Those who worship God in spirit and truth will bear fruit of the Spirit. (Galatians 5:22-23)This who worship idols will bear fruit of idolatry! (Romans 1:22-32)
