Looking to judge the sins of others to feel superior and have one last poke at them is evilly motivated by the devil.
We ought to be broken when we have to confront a believer about their sin. The prayer and hope is that they will weep over their sin and be restored, not to demean them. We weep with them as they grieve over their sin.
I once encountered a woman who had been broken over her sin, she shared this sin with her brother and his response was, in a mean voice; "why did you do it?" He loved that she had fallen and that he could feel superior. There is no love in this! By the way, what could be that woman's answer to her brother? She might want to respond with this; "I enjoyed the sin and wanted to do it, but now I am sorry I did and do not ever want to do it again."
No one can deny they do sin because they want to enjoy it. Of course, we enjoy sin for a moment, but if we are born again we hate what we did when we give into temptation.
The woman who sinned and was reviled by her arrogant brother never wanted to share anything with him again. What did he accomplish? She was not going to sin again and didn't, but the brother destroyed any potential of having a relationship. There was no sorrow in overreacting that way, even a sense of justice in his mind kept him in a state of contempt. We know this because since that encounter the brother had treated her with contempt and rudeness, as though he had never sinned in all his life. By the way, the sin wasn't even against him, it was against someone else he knew.
Galatians 6:1-2 "1 Brothers, if someone is caught in a trespass, you who are spiritual should restore him with a spirit of gentleness. But watch yourself, or you also may be tempted. 2 Carry one another's burdens, and in this way you will fulfill the law of Christ.…"
Perhaps the greatest temptation of the one confronting a trespass is the sin of pride that "they would never do such a thing."
Brokenness over the fall of another person is love, and restoring them with kindness is also love. You see "love" is the first fruit of the Spirit of Christ. We are grieved when our brothers and sisters fall, our greatest desire is for them to repent and be restored as though the sin never happened. After all, Christ forgets our sin when we confess to be cleansed, how much more would a person who knows they are also a sinner want to forgive and restore the one they love.
Galatians 5:22-23
"22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law."
An arrogant person could never be evangelistically minded. How could they have a burden for lost sinful souls when they cannot love the person standing right in front of them?
