Act 1:8-“But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.” I would like for us to consider some lessons this week on the Holy Spirit. Of course we know that the Holy Spirit is the third person of the Godhead. Jesus had earlier commanded the disciples in Luk 24:46-49-“And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.” He is the power of the church. It was inconceivable that the Church could go forth and do the work Jesus had commanded without the empowering of the Holy Spirit. Let us focus this morning on the power of the Holy Spirit to witness. Jesus did not say they would be empowered to organize, to build buildings, to buy property, to amass wealth, to become famous, to entertain, to do benevolence, to do community improvements, but to witness! Does that amaze you and challenge you.? Does the Holy Spirit not empower us to do all the functions of the church? Of course! But the main emphasis of Jesus in our verse is to witness. Albert Barnes adds-“The word “power” here refers to the help or aid which the Holy Spirit would grant; the power of speaking with new tongues; of preaching the gospel with great effect; of enduring great trials…The apostles had impatiently asked him if he was then about to restore the kingdom to Israel. Jesus by this answer rebuked their impatience, taught them to repress their ill-timed ardor; and assured them again of the coming of the Holy Spirit…”. We know this promise was fulfilled in Acts 2. A scared and weary group of disciples became empowered, bold, and assertive and began to “turn the world upside down…”. (Acts 17:6). Of this witness John Gill relates-“…of the person of Christ, of his deity and sonship, of his incarnation, his ministry, and his miracles, of his suffering and death, of his resurrection from the dead, and his ascension to heaven. This was to be their work, and what belong to them, and not to enquire about a temporal kingdom, and the setting up of that, and the times and seasons of it; their business was to testify of the sufferings of Christ, and the glory that followed, and to preach a crucified Jesus, as the only Saviour of lost sinners…”. As so it is ours today! The main job of the church is to preach, teach, and show forth Jesus in the power of the Holy Spirit. Let us “be about our Father’s business…”. Hallelujah!
