Life for the mission of the Lord

Acts 20:13-24
Paul told to the elders of the church Ephesus. "However, I consider my life worth nothing to me, if only I may finish the race and complete the task the Lord Jesus has given me - the task of testifying to the gospel of God's grace."
Paul has declared to both Jews and Greeks that they must turn to God in repentance and have faith in our Lord Jesus.
Before he left Ephesus, Paul wrote 1 Corinthians. From Macedonia he wrote 2 Corinthians. From Corinth he wrote the letter to the Romans. It is likely he also visited present-day Albania and Yugoslavia at this time.
On the way back from Greece, Luke joins Paul at Philippi, where they begin their voyage to Jerusalem, picking up the party waiting from them at Troas.

Paul's address to the elders from Ephesus is the only one in Acts which was given to Christians - and the only recorded address by Paul which Luke actually heard him give.
Why?
Paul was living for the mission of gospel from the Lord.
Paul wanted go to Jerusalem in time for the Feast of Pentecost, because Pentecost is the day Holy Spirit come upon Apostle in Jerusalem.
If Paul went to Ephesus may communicate with brothers their and comfort them, but Paul decided facing the hardship way to Jerusalem, he doesn't care his life but the mission on him.
How?
Paul is our example to learn for the mission what he devoted. What can I do now for the Lord? Do all my heart, my strength and my mind to serve the Lord, serve people.
