When we pray for the power the Paul promises we must remember that the power he wishes for us is the power to show Grace. It is that Grace that God showed to us before asking anything of us that demonstrates how we should lead with grace.
Ephesians is a letter from the Apostle Paul to the church he planted in Ephesus. They are growing but have lost some of the fire they had for God. Paul reminds them that they need to grow in Gods vision for their lives.
