Settling every Bible based question or studying every Bible based topic can hardly be resolved with a single verse every time, but there are times when a single verse is so clear and concise in what is being said, the point cannot be missed by any honest Bible student.
For example, take the question and topic of the necessity of water baptism in relation to salvation. For every verse that reveals the truth about water baptism there are some people who try to raise two verses to teach to the contrary. Often these verses contain the concept of “faith” that stands alone, but never a verse containing the words “faith alone” together – see here. The result is a large number of the religious world promoting a perverted and watered-down view of water baptism such as, “You are baptized to show the world that you are already saved, not to be saved.”
So what is the truth about the necessity of water baptism? Well to be honest there is not a single verse that teaches you about all the details of what happens for us or to us during our submission to God in the waters of baptism, but there are plenty of verses that reveal its necessity; one of these verses being 1 Peter 3:21 which says, “There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ,“.
Try as hard they may, to remove the truth about the necessity of water baptism from the Bible would result in individuals removing entire pages from numerous pages in the New Testament and several more from the Old Testament when you include the types and shadows of God’s plan of salvation revealed in the life, the teachings and the last will and testament of Jesus Christ (Mark 16:15-16).
