"God" (theos) denotes the divine nature, the essence of what it means to be a deity. Here are some essential facts regarding God's nature. There is only one God (Dt. 6:4; Jas. 2:19), that is, one unified divine nature consisting of the sum total of those qualities that distinguish a being as divine.
Some of the non-moral traits of Deity are: eternality, omnipotence, omniscience, and omnipresence. Moral qualities of God include: holiness, love, benevolence, justice, and mercy.
Three distinct personalities share the divine nature. These individuals are identified in the New Testament by their roles in humanity's redemption: Father, Son, and Holy Spirit. The Father is God (Eph. 1:3), as is the Son (Jn. 1:1; 20:28; Heb. 1:8), and the Holy Spirit as well (Acts 5:3-4).
We cannot prove God's existence in the same way we can prove that the earth is a sphere or that water freezes at 32°F at sea level. Nonetheless, a prima facie case for his existence is so overwhelming that only the fool denies it (Psa. 14:1; Rom. 1:20ff). See ATHEISM.
God's existence may be argued for logically based on:
As atheist Jean Paul Sartre conceded: "If there is no God, nothing is wrong."
