The Bible does not seek to prove that God exists. Rather, its authors wrote the Scriptures with the knowledge that He does exist. His attributes, for this study, are divided into two sections: physical and moral. His physical attributes describe such characteristics as His holiness, omnipresence, and unchangeableness. His moral attributes describe such characteristics as His love, mercy, compassion, patience and faithfulness.
To the New Testament believer, God's final revelation of His attributes is found in Jesus Christ. If we want to understand fully who God is and what He is like, then we must look to Jesus, who was God in the flesh. Colossians 2:9 (KJV) states, "For in him dwelleth all the fullness of the Godhead bodily." The writer of Hebrews writes, "In the past, God spoke to our forefathers at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word." (Hebrews 1:1-3 NIV).
To Philip's inquiry, "Show us the Father and that will be enough," Jesus responded, "Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father." (John 14:8-9)
