For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the publicans so?
There is no reward if we love those who love us, Jesus said that even unconverted tax collectors are capable of doing that. That type of love requires no divine power. If our standards are no higher than the world’s, it is certain that we will never make an impact on it.
