Several factors all demonstrate with clarity and strength that baptism, as a church ordinance, must be conducted by the immersion of a believing Christian in water upon confession of his faith and evidence of his repentance for the purpose of signifying to all the world his identification with Christ in His death, burial and resurrection.
The bodily resurrection of Jesus Christ from the dead is the crowning proof of Christianity. If the resurrection did not take place, then Christianity is a false religion. If it did take place, then Christ is God and the Christian faith is absolute truth.
The terms "evening" (Hebrew ereb) and "morning" (Hebrew boger) each occur more than one hundred times in the Old Testament and always have the literal meaning – that is, the termination of the daily period of light and the daily period of darkness, respectively. Similarly, the occurrence of "day" modified by a numeral (e.g., "third day") is a construction occurring more than one hundred times in the Pentateuch alone, always with a literal meaning. Even though it may challenge our minds to visualize the lands and the seas, and all plants, being formed in one literal day, that is exactly what the Bible says! We are not justified at all in questioning either God’s power to do this or His veracity in telling us that He did.
