The apostles in the early Church demonstrated so much power and excellence of the Spirit as they proclaimed the Gospel and turned many to righteousness. Preceding their exploits and spiritual feats was the fulfilled promise from Jesus, which we read in our opening verse. That was their secret and unparalleled advantage: the Holy Spirit coming to live in them.
Take for example, Peter who hitherto, out of fear, denied Jesus before a young girl; after he received the Holy Spirit, the same Peter fearlessly preached the Gospel to a teeming crowd with three thousand souls giving their hearts to Christ at once (Acts 2:41).
The same thing happened with the Apostle Paul after he received the Holy Spirit. Acts 9:20 tells us he went straight to the synagogues and began to preach that Jesus was the Son of God. In 1 Corinthians 2:4, he said, “And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power.” He so demonstrated the power of God that on the Island of Malta, the natives concluded that he was a god (Acts 28:1-6).
Today, the same Holy Spirit lives in you. He came to make you a witness of the glory, power and the reality of the Kingdom of God. 2 Corinthians 3:6 (AMPC) says, “ Who has qualified us as ministers and dispensers of a new covenant the Gentiles, unto whom now I send thee, 18 To open their eyes, to turn from darkness to light, and the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. ||
2 Corinthians 3:5-6 Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency of God; 6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life. ||
Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature. ||
