though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: (Philippians 3:4, ESV)Some have put their confidence in the flesh. Paul has abandoned this, but to make sure that nobody thinks that this lack of confidence in the flesh is because of shortcomings in Paul's history, he is going to lay that to rest. If there is anyone that could have confidence in the flesh, it is Paul.
For what is our hope or joy or crown of boasting before our Lord Jesus at his coming? Is it not you? (1 Thessalonians 2:19 -- ESV) Three things mentioned here... "hope" ... "joy" ... "crown of boasting" ... Hope - What does Paul have his sights set on? Joy - What is it that brings Paul joy? Crown of Boasting - That Olympic Wreath of Glory that is placed on his head? It is these people. It is his children in the faith. They are Paul's Hope and Joy and Crown of Glory when Jesus returns.
