With God, the good and the perfect are never in conflict, one need never be abandoned in favor of the other. In today's Gospel reading Christ tells us that the greatest good for every human person is to "be perfect" as our heavenly Father is "perfect".
Sometimes we let the bad get in the way of the good. In the Sacrament of Confession, the Lord restores to us the good of grace lost particularly in the commission of mortal sin, so that we may continue through Him, with Him and in Him, to pursue the perfect by way of the good.
Praised be Jesus Christ!
