When Peter received the Holy Spirit on the Day of Pentecost, he immediately stood up and preached – and 3,000 people responded and received Christ. This shows us something of the power behind Spirit-filled preaching.
The Lord's Will be done
Finish the race, complete the task
Acts 20.24 says: “However, I consider my life worth nothing to me; if only I can finish the race and complete the task the Lord Jesus has given to me – the task of testifying to the gospel of God’s grace.”
What a powerful statement. Paul considered his own life nothing compared with finishing the race and completing the task God had given him. All the suffering, all the hardship, and all his personal desires were secondary to that one purpose.
