Romans 15:1-16

Paul again emphasizes that we should not live solely for our own pleasure, but that we should strengthen one another and accept one another just as Christ accepts us. We should hold each other accountable, but we need to make sure that we are correcting one another out of love for one another.

Older siblings have likely heard more than once in their lives to be an example to their younger siblings. It is the same with brothers and sisters in Christ. More mature Christians have a responsibility to set an example for those who are new(er) to the faith and look to them for guidance. Mature Christians should realize this is a position of servitude - not lordship - and act accordingly. Advice or criticism should always be based on solid Biblical teaching and come with an attitude of love, not condemnation or superiority.
