Exodus 22:20 He that sacrificeth unto any god, save unto the LORD only, he shall be utterly destroyed.
God will not share His glory with another. God will not be one of your gods. You will love and honor Him alone, or you will not be honoring Him. God’s people were taught that they were to destroy anyone that would choose to sacrifice to another god.
God wants to be God. He doesn’t want to be one of the gods. He wants your complete life and allegiance. That is what any real God would wish. To love God is to love God and none other. To love God means to turn your back on any and everything for Him. We are to die even to our own lives and live for Him.
