To treat an imperfect brother (or sister) impatiently is to advertise our own imperfections.
Teach us, O God, that nothing is necessary to Thee. Were anything necessary to Thee that thing would be the measure of Thine imperfection: and how could we worship one who is imperfect? If nothing is necessary to Thee, then no one is necessary, and if no one, then not we. Thou dost seek us though Thou does not need us. We seek Thee because we need Thee, for in Thee we live and move and have our being. Amen.
