Sometimes when you have what appears to be a successful service you don't notice God isn't there. But His presence among us is not automatic. When we become self-sufficient and forget to consult God about what He wants to do, He is grieved. He will resist the pride that causes us to do our own thing instead of His thing by lifting His grace. And when He lifts His grace, everything we are doing begins to fall apart.
Judgment is another form of pride.
When we judge someone, we forget what we ourselves would be like without God's grace. Only God is qualified to judge, for He is the only one who knows the heart of a man. Instead of boasting or judging, let's learn to prefer one another.
