The Name
God used different titles, such as "God Elohim," "El Shaddai," "Jehovah," and especially "Jehovah Lord", the redemptive name in the Old Testament.
"For unto us a child is born, unto us a son is given: ... and His name shall be called Wonderful, Counselor, the Mighty God, The Everlasting Father, The Prince of Peace" (Isaiah 9:6). This prophecy of Isaiah was fulfilled when the Son of God was named, "And she shall bring forth a son, and thou shalt call His name JESUS: for He shall save His People from their sins" (Matt. 1:21).
"Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved" (Acts 4:12).
Water Baptism
The scriptural mode of baptism is immersion, and is only for those who have fully repented, having turned from their sins and a love of the world. It should be administered by a duly authorized minister of the Gospel, in obedience to the Word of God, and in the name of our Lord Jesus Christ, according to the Acts of the Apostles 2:38, 8:16, 10:48, 19:5; thus obeying and fulfilling Matthew 28:19.
