Being 'saved' is a phrase that is used very frequently nowadays. In Biblical terms it means to be granted immortality at judgement - saved from eternal death. This will be covered in more detail in future sections of this site, God willing. Again The Kingdom of God will be discussed elsewhere on this site, which leaves us with the topic of Baptism. The Greek word from which we get 'baptism' essentially means 'submerge'.
Baptism is full immersion in water.
If baptism did not require submergence, as the word itself suggests, then it would not have been necessary to go down into the water. The order is important. Belief must come before baptism. In the New Testament we only read about people who believed being baptised. There are no recorded examples of unbelieving people being baptised.
