Partnership is more than sharing. It is holding things in common, a contract relationship where all have equal interest and obligation. Paul had invested himself in them so that they may know the Lord and grow in grace. His prayer is that God would finish His work of setting them apart for Himself. He characterizes God as the “God of peace.” God is the party responsible for converting those who had formerly been enemies to now be at peace with Him. He works that peace by providing His Son to atone, by transforming the rebel heart into a sanctified heart by faith, and by sustaining believers until they are ushered into glory. This is the sanctifying grace that Paul is talking about.
At JCY we believe that prayer can change things, especially interceding for other’s needs through prayers helps us to share the love and fellowship with others. Individual prayer is essential, yet there is no denying that God wants us to bring other people into our prayer life. Jesus makes this clear when He instructs that if two of you on earth agree about anything you ask for, it will be done for you by My Father in heaven. For where two or three come together in My name, there am I with them (Matt. 18:19-20).
