Do you treat God like a vending machine? Does your relationship to God consist of your trying to manipulate Him to get what you want? That is serving God for what He does for you, and not for who He is. I believe this is a rampant problem in Christianity today and I have been guilty of it many times.
A lot of us look at the blessings in the Bible and the deliverance from Hell and say, "Sign me up!" We know what is right, and we want to do it, but deep in our hearts we are only committed as much as God keeps supplying blessings. God does use blessings to bring us to Him, and to teach us of His goodness, but He desires for us to have a deeper relationship to Him.
In Deuteronomy 6:5, God commanded Israel, "And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might." God didn’t want Israel just to love what God gave to Israel, He wanted Israel to love HIM. When we read the history of Israel, we find that time and time again they turned away from God. They loved other things, and God brought judgment. They never truly received everything God wanted for them because He couldn’t reward their disobedience.
How about you? Are you seeking God because of who He is? Or do you just want God for what He does for you?
I would challenge you, search your heart today. Are you loving God? Or just the blessings He gives you? If you are serving God just for what He gives you, it isn’t really serving God. You are living out of selfishness and not love. If you find yourself lacking, I would encourage you to ask God to change your heart. Ask Him to teach you to love Him for who He is. God can and will help you change your heart.
"And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment." – Mark 12:30
