The Bible reveals God as the only infinite and Eternal Being, having no beginning and no ending. He is the Supreme Personal Intelligence, and Righteous Ruler of His universe. He is life, and therefore, the only source of life (John 5:26).
Man is natural and cannot know God by wisdom (Job 11:7). God is a person and can be known only by revelation. In the Old Testament He revealed Himself to and through His prophets? In the New Testament He reveals Himself through Jesus Christ (Hebrews 1:1-3)
1) The existence of God (Hebrews 11:6): But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
2) The Bible reveals God as personality. He is called “the living and true God” – One possessing self-consciousness and self-determination. His personality is shown in what He does, such as:
Only a personality can love, hate, care and grieve; therefore God must be a living, eternal and personal being.
3) The Nature of God (I John 4:8): He who does not love does not know God, for God is love.
God is described 4 ways in the Bible. Since God cannot be defined, they are incomplete. However, they do throw light upon the nature of God. They are:
4) The attributes of God reveal His nature. Do not think of His attributes as abstract, but as vital mediums through which His holy nature in unveiled – attributes ascribed to Him, such as:
God is everywhere but not in everything. If God were in everything, man could worship any object and he would be worshipping God. God is spirit. (John 4:24)
5) Grace is the love and mercy of God in action. Mercy is negative, and love is positive; both together mean grace. To show mercy in love is grace. God showed mercy in love when He sent His Son to bear our sins in His own body on the cross (John 3:16).
6) The Trinity of God (Matthew 3:16-17): 16) “When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. 17) And suddenly a voice came from heaven, saying “This is My beloved Son, in whom I am well pleased.”
By the Trinity of God we mean His tri-personal existence as Father, Son, and Holy Spirit – three distinct persons in one God.
Even creation implies the doctrine of the Trinity.
