How do we know that Christians should restore each other?

In Galatians 6:1, Paul instructs, 'Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such a one in the spirit of meekness.' This highlights our responsibility as believers to support and uplift each other in times of sin or weakness. The act of restoration reflects the grace we have received from Christ; just as He restored us from our faults, we are to do the same for our brethren. This call to restoration is rooted in love and humility, acknowledging our own struggles and extending the mercy we've received to others.
