Should infants also be baptized?

Yes. Infants as well as adults are included in God’s covenant and people, and they, no less than adults, are promised deliverance from sin through Christ’s blood and the Holy Spirit who produces faith. Therefore, by baptism, the sign of the covenant, they too should be incorporated into the Christian church and distinguished from the children of unbelievers. This was done in the Old Testament by circumcision, which was replaced in the New Testament by baptism.
