When Paul was considering his fate in prison, he wrote to the church in Philippi with confident hope that he would be freed. In Philippians 1:25-26 he tells them what he wanted to do on his release:
…[I will] continue with all of you for your progress and joy in the faith, so that through my being with you again your joy in Christ Jesus will overflow on account of me.
His aim is them glorying abundantly in Jesus, full of joy in Him.
