Matt 7:1

7:1 Judge not. Jesus prohibits one kind of judging, but approves a different kind. Condemning others for their faults is failure to exercise forgiveness (6:14, 15); only a gentle and humble criticism that first recognizes one’s own greater faults can help. There is also a necessary, discerning kind of judgment that does not condemn but distinguishes unbelief from belief (v. 6). The method of discernment is given in v. 16.
