The Bible gives all believers the authority to point out the sins of other who profess a belief in God. The term is called “rebuking.”

“Do not hate your brother in your heart. Rebuke your neighbor frankly so you will not share in his guilt." Leviticus 19:17

Preach the Word; be prepared in season and out of season; correct, rebuke and encourage—with great patience and careful instruction. For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. They will turn their ears away from the truth and turn aside to myths. But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry. 2 Timothy 4:2-5

As iron sharpens iron, so one man sharpens another. Proverbs 27:17

It’s all part of our call to be brothers and sisters in Christ. We are helping others by pointing out their needs, in a spirit of love and care. Sure it’s not easy, but we all need some accountability.

We must remember to speak to them in humility, realizing that we ourselves are sinners too, not perfect, and some day they may be pointing out our faults. We must do it with their best interests in mind, not our own.
