Throughout history, people have attempted pit love of God against love of neighbor. Jesus shatters this false dichotomy by teaching that each is an expression of the other.
If my actions to express love for God do not reflect my love for neighbor, they are misdirected. My love for neighbor ought to express my love for God, too.
O God, may I show my love for You by loving my neighbor. May my love for others show that I am loved by You.
