Unless your righteousness exceeds that of the scribes and the Pharisees, you will never enter the kingdom of God.
Not too long after I met the girl who became my wife, I suddenly became aware that my wants had changed. My girlfriend's wants had become my wants.
Of course I was in love. Being in love makes everything easy. It was so easy to be generous and kind. Anything that might have annoyed me in the past, now was endearing.
So how does a person achieve the righteousness that the Law demands?
Only by loving, by being in love, with God!--which is the first commandment. Deut 6:5, Matt 22:38
