While I agree with infant baptism, I disagree with the way this booklet has been advertised."It avoids the baptism debate while graciously presenting the story of God’s faithful provision, protection, and promise of deliverance for his people given through the sign of the covenant." That's just too simplistic - didn't the vast majority of Israelites die in the wilderness in unbelief while their circumcision was not really circumcision of the heart? Most of Europe baptized their babies; but their churches are now museums. Let's have some humility and credibility with the way that we present paedo-baptism. Neither infant circumcision nor infant baptism were/are a saving grace by any stretch of the imagination - grace alone, faith alone, God's Word alone, Christ alone, to the glory of God alone. Not all Israel is Israel - in other words, not all who are outwardly marked as being of Israel are of Israel fully; so also, not all who are outwardly marked as being Christians are Christians fully. However, it is important to be marked. Whether an OT Esau or a NT apostate who was "with us but not of us" - the marking is important, but it is not a grace that saves. That helps to make sense of the apostasy passages in the NT.
