We love Him first and foremost

What does the LORD your God require of you, but to fear the LORD your God, to walk in all his ways, to love him, to serve the LORD your God with all your heart and with all your soul. (Deuteronomy 10:12. ESV)

We are to be loyal to God and His Word. This expectation of loyalty is seen in the Old Testament, based on the covenant God made with Israel—that He would be their God, and they would be His people. As such, they were to keep God’s commands; and God, in turn, would give them a land to dwell in and call their own, and care and provide for them.
 The same expectation of loyalty to a covenant is expressed within the New Testament. Jesus shedding His blood for us has brought about a new, better, and eternal covenant between God and His people. We hear the expectation of love and fidelity to Jesus when He says that loyalty to Him surpasses loyalty to family: “Whoever loves father or mother more than me is not worthy of me, and whoever loves son or daughter more than me is not worthy of me.” (Matthew 10:37)
 The principle that Jesus lived and which Scripture teaches is that our first priority is to love God with all of our hearts. We love Him first and foremost, and then we love our parents, spouse, children, family, etc. Loving God most does not take away from the deep love we have for others, but it puts it in proper perspective. —Peter Amsterdam [1]

 Your priorities must be God first, God second, and God third, until your life is continually face to face with God. —Oswald Chambers
