The Bible tells us a lot about the love of our brothers in Christ Jesus, about loving our neighbor as ourselves, about coping with them with all patience and love, and this is not something negotiable, it is something that we should practice in everyday life, because through this we show that we are truly saved people and that we do not pretend to be better than others.
The first thing we should know is that Christ bore us even though we deserved hell, He did not look at our defects, which are many, but He looked at us with eyes of tenderness to save us. In the same way we must manifest that love for our neighbor.
There are believers who do not raise their brother when they see them fall, but they begin to judge them and treat them with indifference, but that should not be the attitude, since if the righteous fall God raises them, then, who are we to judge that creature that God raises with love? Of course, we are talking about people who know how to recognize when they make a mistake and humble themselves before God.
