Does any but God possess the right of condemnation? Who are we to judge others? Condemnation of the sin of unbelievers by believers is not evangelism, it’s damaging, hateful, and drives people away.
In the same way that the Lord forgave you, you should also forgive. To the same degree. And how did God forgive you? Unconditionally.
When we talk about others’ shortcomings, we should have an attitude of forgiveness and desire for them to change, not one of rejecting them as a person.
God uses our time on this earth to refine us, and it takes a lot of work, a lot of heat, and a whole lot of patience.
We are meant to be in community; the early church was built around the idea of doing life together. Are your doors open?
