Paul lived with integrity. As he faced prison for his testimony he declared in Acts 24:16:
This being so, I myself always strive to have a conscience without offense toward God and men.
This statement Paul made in Acts should stir all of our hearts. Paul said that he always strove to not have any conscious un-repented of sins in his life.
That is integrity.
Integrity is a beautiful word to describe the life of a believer who has great power in their prayers.
Webster defines integrity with three statements and corresponding words:
1 : firm adherence to a code of especially moral or artistic values: incorruptibility
2 : an unimpaired condition: soundness
3 : the quality or state of being complete or undivided: completeness
Each of those elements is what God says we are to have in our lives and to pray for in the lives of those we love.

As we turn to Ephesians 4, we are listening as the Apostle Paul sat chained to the wall and to a guard in a Roman prison, and he prayed. His prayers fanned out across the ancient world, encouraging struggling pastors, strengthening church planters, stirring the hearts of new believers, and on and on went the stream of prayers.
Paul never ceased to pray until the Roman executioner severed his body and his spirit soared into the presence of God. Up to that moment, he labored night and day in prayer.
