His point is that no one is truly free; we are either a slave to sin or to God. He exhorts believers to choose the right way, God's way, which is the only way that leads to eternity.
PAUL'S PRAYER FOR THE CHURCH
For this reason, I bow my knees and pray to the Father. It is from Him that every family in heaven and on earth has its name. I pray that because of the riches of His shining-greatness, He will make you strong with power in your hearts through the Holy Spirit. I pray that Christ may live in your hearts by faith. I pray that you will be filled with love. I pray that you will be able to understand how wide and how long and how high and how deep His love is. I pray that you will know the love of Christ. His love goes beyond anything we can understand. I pray that you will be filled with God Himself.
God is able to do much more than we ask or think through His power working in us. May we see His shining-greatness in the church. May all people in all time honor Christ Jesus. Let it be so.
Ephesians 3:14-21
