The Greek word denotes a question, an inquiry. Its meaning is very much disputed. The right meaning seems to be as indicated by Alford — "the seeking after God in a good and pure conscience." It is this that governs the proper Christian life. This kind of question, which asks for something, can be considered an appeal or demand. Peter's thought here may be that baptism is the baptized one's appeal to God for a good conscience toward God. Baptism, as a symbol, a counterpart of our belief in all the accomplishments of Christ, testifies that all the problems we have before God and with God have been solved. Hence, it is also a testimony, witnessing that in our conscience there is no more accusation and that instead we are full of peace and are confident that we have been baptized into the Triune God (Matt. 28:19) and have been organically united with Him through the resurrection of Christ, that is, by Christ in resurrection as the Spirit of life. Without the Spirit of Christ as its reality, baptism by water immediately becomes an empty and dead ritual.
