When we gather ourselves together to hear the preacher preach, it is more than just listening to God’s man speak. God has purposed to reveal hidden mysteries (Colossians 1:26-27) through the assembling of the brethren. In Acts 4:31-34, the power of God is revealed in boldness. The group that was assembled together had great expectation, because when they prayed the place shook and they were all filled with the Holy Spirit. They were of one heart and one soul and had all things in common. Great power gave the Apostles witness of the resurrection of the Lord Jesus. Great grace was upon them all.
The Word of God in Hebrews 11:15-16 states that we seek a new country and must be mindful of our heavenly substance in Christ so that we don’t have occasion to return back to what we have come out from. By assembling ourselves, we give our Beloved cause to draw us into His chambers (Song of Solomon 1:4), so that we may eat of His fruit (Song of Solomon 2:3), and so that His right hand may embrace us (Song of Solomon 2:6). We assemble together so that we may abide under the shadow of the Almighty and dwell in the secret place of the most High (Psalm 91:1).
When great grace is upon us as we assemble together, we can think in terms of headship and can receive in terms of the Throne; but if we forsake that assembly of headship, we forfeit the ministry of the Holy Spirit in the corporate fellowship of God’s mind.
