You must be baptised to be saved. Have you ever heard that great news! What could be simpler. Go down to the water and get changed! It is true that you must believe first. Your conscience must be affected by that act of baptism. You also must go down under the water to be changed. Romans 6 explains that in a figure, it is as if we die and are buried, and then connect with Christ's resurrection by coming back up out of the water. But you first must believe the truth.
The truth to be believed is the gospel of the kingdom and name of Jesus Christ. When this is understood, and heartily received, it produces a disposition of mind, such as was in Abraham and Jesus, and which is called repentance. Believers, so disposed, are the begotten of God, and have become as little children. They believe "the exceeding great and precious promises", together with the things testified concerning the sufferings and resurrection of Jesus. He fell into a deep sleep; and, while thus unconscious and insensible, his side was opened by a spear, and forthwith rushed blood and water. Being awakened out of his sleep, he was built up a spiritual body, flesh and bones; and, by his ascension, presented to the Father as the federal representative of his church. This is the aggregate of those, who, believing these things, have been introduced into Christ through the laver of the water; according to the saying of the scriptures, "Ye are all the children of God in Christ Jesus through the faith. For as many as have been baptized into Christ have put on Christ" "Ye are all one in Christ Jesus. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
