Why has God designed and purposed that our great destiny is to know Him? What is the knowledge of God for? Why does God mean us to know Him and to grow in the knowledge of God? And there is only one answer that Scripture gives us to that: and that is that we might worship Him. Everything will disappear as we enter His presence and glory, except this. It is the chief business of the church of Jesus Christ in this world, because it is the permanent occupation of the church of Jesus Christ in the world to come, that we should worship God. So says Jesus to the woman of Samaria: The Father is seeking worshipers. When God began to seek you and then find you in Jesus Christ, and drew you to Himself, He was seeking worshipers. The Apostle Paul tells us that it is the mark of the people of God, one of the great marks of those who are His true circumcision in Philippians 3:3f.: we are the circumcision, that is the true people of God, who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh. . . .
What is the ultimate activity of the people of God? It is that we might spend ourselves, heart and soul and mind and strength, in worshiping Him.
