Let me throw this out there and see what some of you think...
Now that we have a better idea of what it means to be spiritually alive or spiritually dead, notice that the apostle Paul said that he "died" as a result of becoming aware of sin, and notice that he was alive until that happened (verse 9):
Romans 7:1: "Do you not know, brothers--for I am speaking to men who know the law--that the law has authority over a man only as long as he lives [zao in the Greek]?"
Romans 7:2: "For example, by law a married woman is bound to her husband as long as he is alive [zao in the Greek], but if her husband dies [apothnesko in the Greek], she is released from the law of marriage."
Romans 7:3: "So then, if she marries another man while her husband is still alive [zao in the Greek], she is called an adulteress. But if her husband dies [apothnesko in the Greek], she is released from that law and is not an adulteress, even though she marries another man." ...
Romans 7:9: "Once I was alive [zao in the Greek] apart from law; but when the commandment came, sin sprang to life and I died [apothnesko in the Greek]."
In verse 9 , notice that Paul didn't say, "Once I was happy apart from law," and he didn't say, "Once I was at peace in my conscience apart from law," and so on. Paul said, "Once I was alive apart from law," and then he said that he "died" when he learned of the commandments. In verses 1 to 3, Paul talked about individual people being alive or dead, and then in verse 9 he talked about himself being alive and being dead using the same Greek words as in verses 1 to 3. In verse 9 he was talking about his own personal death. When Paul said that he died, he obviously didn't die physically because he wouldn't have been able to write the above passage. He died spiritually, meaning that he would not have gone to heaven and would not have had eternal life with Christ if he had physically died in that state. Here's what a Bible commentary says about this verse:
"Evidently the apostle was speaking of his personal experience as a child and perhaps even a youth prior to his awareness and understanding of the full impact of God's commandments. ... The result was that the principle of sin within made its presence and power known (it sprang to life) in his violations of the commandment. As a result Paul died spiritually" (The Bible Knowledge Commentary, Walvoord and Zuck, Dallas Theological Seminary, p.466-467, emphasis added)
According to Paul's example, we were all spiritually alive as children until sin "sprang to life" within us through an awareness or understanding of sin. At that point we died spiritually.
Would you say that this supports the view that infants and young children are spiritually alive and will go to heaven if they die.
