“Our main problem in the Christian life is not that we don’t try hard enough to be good, but that we haven’t thought out the deep implications of the gospel and applied its powerful reality to all parts of our life. Real spiritual growth happens as we continually rediscover the gospel.
The same dynamic explains the primary purpose of corporate worship: to rediscover the mighty acts of God in Christ’s coming to do for us what we could never do for ourselves. We gather in worship to celebrate God’s grip on us, not our grip on God."
