In 1 Peter 3:21, it appears that Peter is saying that we must be baptized in order to be saved. He writes that baptism saves us. But if this is true, then how is eternal life by faith alone and not of works?
It is possible to believe in Jesus for eternal life (and of course, receive eternal life as a result), but still not be “saved” from many of the temporal and physical consequences of sin, or from sickness, or from enemies, or from many of the other negative things that can happen in life.
In Matthew 27:42, people watching Jesus die on the cross said ‘He saved others; but He can’t save Himself!’ So Jesus wasn’t saved. He did not save Himself. This logic is ridiculous, I know. But it is the way many people argue about the word ‘save’ in other contexts of Scripture.
