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 PiperThe engagement of the heart in worship is the coming alive of the feelings and emotions and affections of the heart. Where feelings for God are dead, worship is dead.
