[T]hou 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
Mark 12:30 KJV (portion)
The fool says in his heart there is no God (Psalm 14:1). It takes faith to please God, for one must first believe that God is! (Hebrews 11:6). This is the first, and greatest commandment. The second is like it, you shall love your neighbor as yourself.
Consider for a moment, the Gospel of John. Jesus says in John 16:27 that the Father loves us because we love His son and believe that He came from God. In John 14:15, Jesus says that if we love Him, we will obey Him. And, throughout the final chapters before the crucifixion, Jesus’ repeated command to the believers was this:
A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another.
While the summation of the Old Covenant, all of the Law and the Prophets hung upon these two commands, it should be considered that the goal of the New Covenant is the same, that is also hangs upon these two.
