Blessed Trinity! (The Baptist Catechism, Section 3)

Through Jesus, we come to know our God in three persons.  The Triune God who uses all His mercy and might to save His people from their sins. Q 7. What is God? A. God is a Spirit (John 4:24), infinite (Job 11:7, 8, 9), eternal (Ps. 110:2), and unchangeable (Jas. 1:17) in his being (Ex. 33:14), wisdom (Ps. 147:5), power (Rev. 4:8), holiness (Rev. 15:4), justice, goodness, and truth (Ex. 34:6). Q 8. Are there more gods than one? A. There is but one only, the living and true God (Deut. 6:4, 7; Jer 10:10). Q 9. How many persons are there in the Godhead? A. There are three persons in the godhead, the Father, the Son, and the Holy Spirit; and these three are one God, the same in essence, equal in power and glory (1 John 5:7; Mt. 28:19).
