Pastor Gray preaches from Acts. 20:22-24 about the apostle Paul finishing his "race with joy, and the ministry" he received from the Lord. 

All believers have a purpose and work God destined for them. And whatever it is for you, that's your "church," where you preach the gospel of Christ to those around you. 

It doesn't mean you won't face difficulties, but Christ is with you, helping you fight the good fight of faith and run your race with joy.
