"'Now I commit you to God and to the word of his grace, which can build you up and give you an inheritance among all those who are sanctified.'" NIV translation
Paul was a man of prayer and here he tells the Ephesian elders that he has prayed for them and placed them in God's loving hands. He also encourages them as he reminds them that they have an inheritance. We can take encouragement from this as well because we share in that same inheritance.
"'I have not coveted anyone's silver or gold or clothing. You yourselves know that these hands of mine have supplied my own needs and the needs of my companions. In everything I did, I showed you that by this kind of hard work we must help the weak, remembering the words the Lord Jesus himself said: "It is more blessed to give than receive."'" NIV translation
Paul is encouraging the Ephesian elders to be humble even as they are in a position of leadership. He reminds them that, even though he deserved to be supported, he worked to support the ministry that God had given him. It seems that much of this teaching has been lost on the leaders of today as many are more of the boss behind the desk type instead of the getting your hands dirty actually laboring in the gospel.
Paul, one of the greatest "church leaders" ever, got out of the office and worked to support his ministry. In doing this, he was a great example to the early church as well as to us.
"When he had said this, he knelt down with all of them and prayed. They all wept as they embraced him and kissed him. What grieved them most was his statement that they would never see his face again. Then they accompanied him to the ship." NIV translation
Even as Paul is heading for severe persecution, he bows with the elders from Ephesus to pray for them. What an impression that must have left on the elders!
