In the thread on infant salvation, I keep seeing mention of this "age of accountability". I know what it is, so I am not asking for an explanation. My question is how can this be defended? How can we, in light of Psalm 51:5, which reads, Indeed, I was guilty when I was born; I was sinful when my mother conceived me. (Psalms 51:5 HCSB Emphasis mine) say that an infant is not held accountable? How can we make a case for age of accountability and still be consistent with Scriptures like this one: This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved." (Acts 4:11-12 ESV) or this one: Jesus replied, "I assure you: Unless someone is born again, he cannot see the kingdom of God." (John 3:3 HCSB Emphasis mine) So, what I am asking for here is a Scriptural defense of age of accountability. I want absolutely no appeals to emotion or "God wouldn't"'s. I want a logical and consistent Scriptural defense of this doctrine.
