It is interesting to notice that although the disciples had been taught by Jesus over a period of 3 years, had seen the resurrected Messiah in all His glory and power over a period of 40 days, and had lived life with Him, they were not allowed to go and preach the Gospel until after they had received the Holy Spirit at Pentecost.

1 Corinthians 2.4
¹ When I first came to you, dear brothers and sisters, I didn’t use lofty words and impressive wisdom to tell you God’s secret plan. ² For I decided that while I was with you I would forget everything except Jesus Christ, the one who was crucified. ³ I came to you in weakness—timid and trembling. ⁴ And my message and my preaching were very plain. Rather than using clever and persuasive speeches, I relied only on the power of the Holy Spirit. ⁵ I did this so you would trust not in human wisdom but in the power of God.

What did Paul (the author) say about what he preached?

Where does Paul say the power to share Christ comes from?

Acts 1.8
⁸ But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere—in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”

What is the purpose of the power of Pentecost in our life?
