Mercy for me — justice for everyone else: Our human reaction to the "unfairness" of God.
Yes, it does seem unfair that God loves everyone, even the "worst" of sinners, but he asks us to do the same. The next time you feel the need to judge someone for some wrong you feel they have committed, have a heart like Jesus. Extend your love to them and thank God that He does the same with you.
As for the person who hears my words but does not keep them, I do not judge him. For I did not come to judge the world, but to save it.
