The continuity of "covenant community" from the Old Testament to the New Testament is parallel because not all circumcisized were truly saved. God dealt specially within the covenant community (not guaranteeing every member salvation) but by offering the ordinary means of grace there.

Also, remember that nonbelievers (gentiles) were baptized to get into "Israel" in the Old Testament. The continuity of this throughout all of Scripture, one continuous plan of God has helped me understand infant baptism in context better.

Further, remember that churches that baptize infants also baptize adults by profession of faith. The "signs and seal" ordinance of baptism has more than one aspect, sealing promises to "you and your children" (Acts 2:39).
