“Day by day continuing with one mind in the temple, and breaking bread from house to house, they were taking their meals together with gladness and sincerity of heart, praising God and having favor with all the people. And the Lord was adding to their number day by day those who were being saved.” Acts 2:46-47
You can know the multiplication tables, the history of Civil War battlefields, how to bake a cherry pie, how to win a chess match - you can even know your Uncle Gus - but how can you ever say that you know God? We can know about God, but how do we come to know God as one individual knows another? Is that even possible?
To the child of God who has known the power of God’s forgiveness of past sins, His comfort in and through a severe trial or testing, or His ample provision in time of deep need - the term knowing God has great meaning. The more we focus our attention upon God and what He has revealed about Himself in Scripture - and what we have been privileged to experience by His grace - the greater is our understanding of Him as a “person.” Of course, God is not human but spirit, and those who worship Him must worship Him in spirit and in truth (John 4:23).
God’s desire for each of His children is that they come to know Him, that they have hunger for a relationship with Him. How can one worship a God Whom he does not know? It is foolish for us to think that we can worship God if we are ignorant of Who He is.
The first function of the church is worship, and the foundation of true worship is knowing God.
