Mark 12:28-34God is clear on what he wants us to do: love him above all things. This is also reechoed by Jesus in the gospel, thus, affirming the very heart of the faith.
It is true that Jewish religion enunciated the ultimate laws. But the spirit of the law could only be interpreted through the eyes of God's beloved Son - Jesus Christ.
First, to love God above all things - demands utmost total and unconditional obedience, adoration, and offering of one's life to the Father, the source of all life. Who could ever have authority over life itself? Isn't it God alone? Who could ever hold the key to true life and order? Isn't it God alone? Do we want an organized life? Then follow God!
Second, to love one's neighbor as oneself - to love others means to recognize the other has the same dignity as I have for being a child of God. Thus, to accord justice, respect, as well as honor in the same way as I treat myself becomes an absolute norm, considering that I and my brothers / sisters are created in the image and likeness of God. The second norm is a call to build ourselves as one family of God.
Third, these two laws point to Jesus who fulfilled God's commands and brought it to fulfillment. He is God's perfect priest who offered the perfect sacrifice, himself all for our sake. Now he says to us, "Love one another as I have loved you." This law manifests perfect communion with God and with one another and eradicates all tinge of separation, selfishness, and animosity. This law reflects the true picture of heaven. If we live out this law of love, God resides in us and we in God; we also reside in the hearts of one another.
