John 7:24, NIV: Stop judging by mere appearances, and make a right judgment.

“Do not judge,” Jesus tells us, “or you too will be judged.” After all, it is not our place to judge [to pass sentence on another—to determine we know that a person should be punished and what punishment that person deserves]. But let’s not deceive ourselves. Not judging is not the same as blind tolerance. Jesus tells us to “make a right judgment.” It is necessary for us (in love, in truth, and in the Spirit), to examine the words, deeds, and lifestyles of others and make a right assessment (Mt. 7). How else shall we know how to pray for another? How else shall we restore a brother who has fallen (Gal. 6:1)? How else shall we, once we see clearly, be able to help another to extract the splinter from his eye (Mt. 7)? How else shall we see sin in another’s life, and find in Christ what is needed to meet the needs of the sinner? It is not a matter of you being “without sin” or “casting the first stone.” It is a matter of you looking also to the interests of others (Phil. 2:4), and making yourself available to hear God’s voice concerning the person, and being willing to help however the Spirit would lead.
