“The Lord our God is Lord alone! You shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.”
It is not just a kiss or a hug, or a simple “I Love You” which we normally give to our loved ones to show our love. It is not just saying sweet nothings similar to the content of our love letters. Jesus did not say just to love. He said we must love the Lord with our WHOLE heart and soul and with ALL our mind and strength. If that is the case, then how can I love my wife, children or neighbors, when my WHOLE heart is already given to the Lord? If that is your understanding, then you are correct. BUT GOD IS BEYOND HUMAN UNDERSTANDING.
Moreover, if that is the case, there would be no more second great commandment. In fact, Jesus says the second commandment is like the first. The kind of wholehearted love Jesus is talking about is charity (agape) - loving God for his own sake and all others for his sake. And we do it not by human strength or understanding, but with the divine love that is poured into our heart by the Holy Spirit (Romans 5:5).
When we love others with charity, we are loving God through them. Our every loving act towards them becomes an expression of our love for God. As St. Bernard of Clairvaux has written in his book, “Now a man cannot love his neighbor in God, except he love God Himself; wherefore we must love God first, in order to love our neighbors in Him. This too, like all good things, is the Lord's doing, that we should love Him, for He hath endowed us with the possibility of love. In such wise man, animal and carnal by nature, and loving only himself, begins to love God by reason of that very self-love; since he learns that in God he can accomplish all things that are good, and that without God he can do nothing.”
Almighty Father, may I love You in all things and above all things. May I reach the joy which You have prepared for me in Heaven. Nothing is good that is against Your Will, and all that is good comes from Your Hand. Place in my heart a desire to please You and fill my mind with thoughts of Your Love, so that I may grow in Your Wisdom and enjoy Your Peace.
I am the Lord your God: hear My voice.
