Jesus calls us to a radical love for our brothers and sisters in Christ.
Even our best intentions can be marred by our sin. It is imperative, then, that we always check our hearts and our "fruits" before we address conflict, confrontation, or discipline. Once we have seen the 'beam of wood' in our own eyes will we be able to help a brother or sister see the speck in their own. If we are still blind to our sins, then we will only lead someone else who is blind into a pit.
