What must we do to be saved?
The short answer is that the New Testament has a great deal to say about baptism, from the lips of Jesus himself as well as through his apostles. Now the plain fact is that the Bible is all we have. If we want to know who Jesus was, what he taught and what he commanded his followers to do, we must go to the Bible for the answers. To look elsewhere is to rely on the opinions of men, whether of individuals or of bodies of men in Synods or Councils. What the Bible has to say about baptism must be vital for us. If Christ and his chosen apostles have declared certain things about baptism, then we ought to want to know what they are.
The really important question must therefore surely be: What did Jesus command and teach and what did his apostles do as a result?
“Born of Water”
To Nicodemus, the Jewish leader who came to him by night, Jesus said: “Except a man be born again, he cannot see the kingdom of God”. When Nicodemus took these words literally, Jesus further explained: “Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God” (John 3:3,5). But why should he say, “Except a man be born of water … ” unless it was a clear reference to baptism? John the Baptist had been actively preaching repentance and baptizing many in the River Jordan. Jesus himself had been baptized by John saying, “Let it be so now; for thus it is fitting for us to fulfil all righteousness” (Matthew 3:15, R.S.V.). There can then be no doubt that when Jesus said, “Except a man be born of water …”, he was saying that to enter the Kingdom of God, a man or woman must be baptized.
