Galatians 6:1 Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.
2 Bear ye one another’s burdens, and so fulfil the law of Christ.
This is speaking of the brothers and sisters in Christ. It is not impossible for a Christian to make a mistake and sin in the process. It is very important for that person to be restored to the group as soon as possible. If they repent of the sin then we are not to keep on bringing it up or remembering it. The ones who are stronger in their walk should lead the way in forgiving them. The next temptation may come to the one who leading the way to help the one that had fallen. This person also should repent from the sin committed and should not continue to commit this same sin. This next verse follow the same theme. We should be there for those who are struggling and if necessary carry the load for them. This is symbolic the the man who carried the cross for Jesus. The law of Christ, spoken of here is to love your neighbor as yourself. The load can be much lighter if we can help carry that load.
