“For this is the message you heard from the beginning: We should love one another.” - 1 John 3:11
The message of love was not readily conveyed by the commandments God had given. But as Jesus said, that was their intent. People have hard hearts. They tend to selfishness. Which is understandable, as life is sweet, and so one craves more. But 100 large milkshakes should not be consumed in an hour, but easily in a year, God shows how life can be sweeter.
Service to others is a godly heart. It is humbling, making it easier to continue. Service points the heart in the right direction to walk with God. Selfishness points away from the Lord. Even isolation, which is sometimes what we wish to commune with God, is a selfish retreat if there are others in need.
But the love is like that of family. And family sleep, rest, play and work. It isn’t selfish to tend to your own needs. But we live for family.
