“This is what I told them: ‘Obey me, and I will be your God, and you will be my people. Do everything as I say, and all will be well!’” Jeremiah 7:23 NLT

Do you believe in God? If your answer is yes, do you want Him to be your God? You may be a bit confused at this point, but just think it through. Just because you say you believe in God is He really your God or just one of many. Is He in competition with your career, your spouse, your vacation home, automobile, boat, or your favorite sports team? Does He hold first place on every shelf in your life, and do you obey Him wholeheartedly in everything you do? If not, then He is your God in name only.
The Lord speaking through the prophet Jeremiah to the nation of Israel says, “…. Obey me, and I will be your God, and you will be my people. Do everything as I say, and all will be well!” (Jer.7:23 nlt) This is what the Lord God wanted Israel to do when He led them out of Egypt. He didn’t want their offerings or their sacrifices, he only wanted their obedience. They believed in God, but also had other gods from the desires of their hearts to put alongside the God of heaven. Over time these idols, other gods, began to push the true God out of their lives. The Lord God says of them, “This is the nation whose people will not obey the LORD their God and who refuse to be taught. Truth has vanished from among them; it is no longer heard on their lips.” (Jer.7:28 nlt)
God is not to be the top rung on the ladder of our gods. He is the whole latter from top to bottom and our access to eternal life through Jesus Christ His Son. There is no other way of salvation and there are no other gods able to bring us satisfaction and joy in this life than the true God of heaven. The Lord is not pleased with our misguided thinking that God is our God simply for our weekly church attendance or our five-minute prayers. He wants us to be totally obedient to Him and to have no other gods before Him, the first commandment. Believe God when He says, ‘Obey me, and I will be your God’ and know for sure that He is.
