John's baptism...was a radical act of individual commitment to belong to the true people of God, based on personal confession and repentance... This is one of the main reasons that I do not believe in baptizing infants, who cannot make this personal commitment or confession or repentance. John's baptism was an assault on the very assumptions that give rise to much infant baptism.
John PiperYou may be going through things right now that are painfully preparing you for some precious service to Jesus and to his people. When a person strikes rock bottom with a sense of nothingness or helplessness, he may find that he has struck the Rock of Ages
