In our communal following of Jesus, there are few things that stop us from doing this more quickly than slander and gossip. These are sins of the tongue that James, the pastor (I take it) deals with rather thoroughly and forthrightly in his letter. One of the things God expressly hates is dissension being stirred up in the community. And even those who do it. If this wasn't a problem among God's people, then God's Word/Scripture would not address it.
Another problem I have is nonverbal unacceptance of others. This is done in mostly subtle as well as not so subtle ways. Not including someone in a conversation when there are more than two involved. Interrupting someone when they're talking. Or not saying anything when one is finished, as if what they have to say is not worth acknowledging, or talking about.
We must be careful not to go along with any of this when it happens. Otherwise we become participants in it.
If we have the heart of Jesus, and indeed that's what we're to have more and more by the Spirit, then in our following together, we will never leave another behind. This is not always easy. We must bear with each other's weaknesses. We must be committed to valuing others above ourselves. If we're to really follow Jesus communally.
Last but not least, we must reach out, in love, to those who are sinning in this way. We know we have done the same. Perfection here is not the issue. Though we should hate it when we do sin, and confess it to God, and others when need be. But as we seek to walk in the Spirit, we need to at least pray for such. And perhaps, in love, take them aside, and talk to them about what they're doing. So that there can be repentance, restoration and change. Not easy, but necessary, if we're to really follow our Lord together.
