Matthew 3 tells us about the ministry of John the Baptist prior to when Jesus appeared on the scene. About half of Matthew 3 is John berating the religious leaders of his day because while they came to his baptism, hey did not “Bear fruit in keeping with repentance.” (Matthew 3:8 ESV). In other words, their actions did not correspond with their words.
John’s words apply to us as well. We can claim to be Christians, we can be baptized, attend church, tithe, take communion. But all these are meaningless if we do not bear fruit, which means we change our lives, change our person, change our soul so it is like Christ. We can take all sorts of action that makes us seem to be a Christian but as God tells Samuel: “. . .For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.” (1 Samuel 16:7 ESV).
