Paul opens up by identifying himself as a prisoner for Christ. He felt so strongly toward the Jews and the Gentiles uniting that he even went to prison. As the verses go on, Paul continues to elaborate the role of God in our lives for the Gentile Christians who may have not known the background. The next few verse are just referring back to what Paul had once said about the Gentiles now knowing the "mystery" because they were apart of the body. In verse 6 the Gentiles Christians are now put in the "line up" alongside other believers. They are heirs, members, and fellow partakers of the promise in Christ.
Paul speaks on how he was made a minister not because he chose it but because it was a gift from God. He received his strength from God who was not distant but right there with him.God's grace in verse 8 is simply stated as "unfathomable." We can not measure, out reach, or see the end of His grace. If that isn't hope I don't know what is. God has a plan for us and through Jesus Christ we receive it. He uses us as a church body to tell of His wisdom to those who do not know. This plan that He gives us also brings about boldness and faith and because of that we should stay strong when hard times come.
These verses are a prayer that Paul had started in verse 1 but decided to wait to finish until now. The main focus on the prayer was about the inner life of a believer and their personal relationship with God. The following are the request that Paul seeks in his prayer; 1) inner strength through God and 2) that Christ may dwell in our hearts through faith. In verses 18 and 19 the prayer is more focused on the people having spiritual understanding. He wanted them/us to be filled with the fullness of God. As Christian we sometimes know the unknowable because we have God who gives us wisdom.
God is going to continue to reveal new things to us through Christ. He has been faithful to do so from the beginning and will continue to do so till the end of time.
* May we seek to find new things through His word daily and let Him use us as a church to glorify His Kingdom.
