God’s Attributes (Source: ODB)
We cannot know God unless He reveals Himself to us. An attribute of God is a characteristic that God has chosen to reveal about Himself through His Word. Incommunicable attributes are those that belong to God alone (e.g., omniscience [all-knowing]; omnipotence [all-powerful]; omnipresence [present everywhere]; immutability [unchangeable]; infinite [having no limits]; transcendence [beyond comprehension]).
Communicable attributes are those that human beings can also possess (e.g., compassion, love, mercy, goodness). In Isaiah 55:8-9, God reveals that He is unlike any other being and our finite minds can never fully understand Him (see Job 11:7-9; Ps. 131:1; Rom. 11:33). Throughout Scripture we are told that there is no one like God (see Ex. 15:11; Ps. 35:10; 89:6-8; Isa. 40:25).
