God is committed to building his house. In fact we find that "Unless the LORD builds a house, those who build it labour in vain" Psalm 127:1, and any attempt to build something for God from our strength is foolishness. Jesus has promised that he will build His Church (Matt 16:18) and it is in light of this promise that we are called to become "co-workers with God" (1 Cor 3:9).
