"Put no confidence in the flesh." Paul looks at his life and demonstrates how if there was any merit in being of the tribe of Benjamin, being a Pharisee, being zealous, etc. he would have much to boast of. He points out that our confidence must be in Christ and not ourselves. To glory in God is not stagnant and progress and growth will be seen over the years. May we move to the excellence of the knowledge of our Lord Jesus Christ.
