The big idea for today is that the Church is a divine work accomplished through Spirit-empowered people, so we must lean on the finished work of Christ in order to lean into His unfinished work of building the Church. In the first eight verses, we see all three Members of the Trinity playing a role in the birth of the Church. We also see divinely-appointed people being prepared to play their own parts. Today’s passage sets the stage by looking backward to the finished work of Christ and looking forward to the unfinished work of Church-building. Jesus laid the Cornerstone, and now He’s calling His people to the ongoing work of construction.
