On Sunday, Nov. 26, 2017, Jesus taught us from Mark 12:28-34 that our love for God must have a chain reaction to a love for our neighbors. Augustine’s sermon on “Thou shalt love thy neighbor as thyself” expresses the connection between the first and second greatest commandments beautifully.
“Now you love yourself suitably when you love God better than yourself. What, then, you aim at in yourself (added emphasis: loving God better than yourself) you must aim at in your neighbor, namely, that he may love God with a perfect affection. For you do not love him as yourself, unless you try to draw him to that good which you are yourself pursuing. For this is the one good which has room for all to pursue it along with thee. From this precept proceed the duties of human society.” –
Augustine, Morals of the Catholic (Universal) Church
Our highest good is in loving God; therefore, we love others by discipling them to be happy in God. Very practically, this opens up for us every means available to give others what we have found for ourselves in God.
