When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
The coming of the Holy Spirit is the pivotal moment for launch of the early church. The sound of rushing wind filled the entire house while tongues of fire came in and rested on all of them. There was no one in the room that was not affected by the Spirit. This coming of the Spirit is the “fullness of eternal promise stirring in [God’s] sons and daughters (verse 1)” Jesus promised the Spirit and now God, the Father, has sent another Helper – the Spirit of truth (John 14:15-17).
The first two verses of the song Fullness speak to the promises of God being fulfilled in the coming of the Spirit. The Spirit stirs in each and every person that loves Jesus and calls Him Lord.
The Chorus is a call for the Spirit of God to be made known and fill our houses of worship. Though it is not necessary to call on the Spirit to come, we can call on Him to make Himself known in our lives. We have the ability to know the Spirit because He works alongside us and in us (John 14:17). Powerful things happen when groups of people ask the Holy Spirit to work mightily through them and around them.
Just before the Spirit is given we see a call to be Jesus’ witnesses in our own cities and the ends of the world (Acts 1:8). “And this power within us, we will rise to be Your witness” These tongues, “testifying of the Son (bridge),” show the power of the Holy Spirit and its mission to tell of the “mighty works of God (Acts 2:11)” to the world.
