This particular situation might be confusing: two unique people, who seem to have truth from God are both preaching and baptizing. John the Baptist notices that people seem to be more drawn to Jesus. John's disciples notice, too. John the Baptist reminds them and us that he is not the Messiah, but that he was given the task of proclaiming His coming. He uses the analogy of a wedding.

No Christian believes Jesus' atoning work is just a memory. You'd better not! And let me ask you: are you simply remember...
