God is not some distant cosmic force, out there beyond the stars and galaxies. He is a person with character and personal traits that we can know. Although He is infinite and immeasurable, we can know Him personally through His Son, Jesus Christ. As Max Lucado wrote several years ago, "God Came Near, " through the person of Jesus Christ. In Christ, God took on flesh and dwelt among us. Jesus came to show us, among other things, that God is not an impersonal "What," but a "Who" that we can come to know intimately and personally. We can each enjoy fellowship with God on a daily basis because of what Christ has done for us.
Jesus sends the Holy Spirit, who resides within each of us. The third person of the trinity lives and breathes within us. Through the Holy Spirit the Triune God lives through us. Jesus said, "Behold, I am at the door knocking. If you hear my voice and open the door, I will come in, and we will dine together as friends."(Rev. 3:20)
Through Christ we come to know "Who" God is.
