1 Corinthians 4
4.5 Then each one's praise will come from God. This is an aspect of the whole judging thing that I had not thought about. When we opperate on a "judging system" we begin to look to men for approval. When we judge others (in the sense this passage speaks of) we are part of turning people from looking to God for His approval, to looking to us. This is a very subtle thing to contemplate.
4.13 being defamed, we entreat This is an amazing, Spirit-filled response. It reminds me of Paul's admonition to Timothy to be patient and gentle in dealing with those who oppose.
4.15 instructors ... fathers That is a real challenge. To have the care and committment of a father, rather than just teaching.
4.20 not the word of those who are puffed up, but the power. This is an important distinction to be able to make.
1 Corinthians 5
5.1 It is actually reported that there is sexual immorality among you... It sounds like it was an unusual or scandalous things. O that it would be like that again.
5.12 those who are outside God judges. We should not be suprised when the world acts worldly.
