Thank you for your question.

First let me lay a bit of a foundation.

As we look through the scriptures, we notice that the Bible is divided into two part, the Old Testament and the New Testament. We are currently living in the times of the New Testament or Covenant, however, as Paul the apostle looks at both time periods, he tells us in Romans that people back then and now are justified (made righteous in the eyes of God) by faith in God.

“For what saith the scripture? ‘Abraham believed God, and it was counted unto him for righteousness.’ Now to him that worketh is the reward not reckoned of grace but of debt. But to him that worketh not, but believeth, on him that justifieth the ungodly, his faith is counted for righteousness. … now it was not written for his sake alone that it was imputed to him [set to his account]; but for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; who was delivered for our offences, and was raised again for our justification.” (Romans 4:3-5)

In saying this, Paul shows that both in the Old Testament and in the New Testament, the only way to be made righteous (because we have “all sinned and fallen short of the glory of God” Romans 3:23), is to have faith in God’s way of salvation so they can be declared righteous by Him and Him alone.

In the New Testament, our faith is placed in the Lord Jesus as the sin bearer who is the reality and completion of the sacrifices found in the Old Testament. By His death on the cross He paid the full punishment of sin so that all who place their faith on Christ can be forgiven and declared righteous by faith.

So where does that leave us?

Well, based on the teachings of the apostle Paul, in order for a person to get to heaven they need to believe in God’s way of salvation: believe in the knowledge they had of God in the Old Testament or place their faith on the Lord Jesus Christ for us today.

In other words, when a person is old enough to understand about God, about sin and about the way of salvation provided to them at the time they were living, they could believe God and go to heaven.

BUT, what about those who died before they were old enough to understand the way of salvation God provided? What happens to them?

Well, to be honest, there is nothing much said about such a situation. Likely because the Bible was written so that those of us who are old enough to understand and read can know how we ourselves can be saved. Each one of us who is reading this needs to ask ourselves this question:

                    Am I going to heaven?

It is more important to know that you are going to heaven than to know if a baby, someone else, is going to heaven. However, let us look at a few things which might give us a possible answer for the question at hand.

First of all, we must look at the character of God. God is fair, “just, and the justifier of him which believeth in Jesus.” (Romans 3:26b). He judges all sin and always does what is right and has provide a way of salvation for those of us who are old enough to believe. He is also a God of mercy and grace and He “is long suffering to us-ward, not willing that any should perish, but that all should come to repentance.” (2 Peter 3:9)

From these and many other verses, we should understand that although we don’t have specific teaching about where a baby goes when they die, we can be sure that God who is “just” and “not willing that any should perish” will do what is right with them.

There is one verse in the Old Testament, however, which seems to hint that they will go to the place of comfort and not the place of suffering.

First of all let us ask a questions. King David, when he died, where did he go? Well, as an Old Testament believer from what I understand from the bible he went to the place of comfort, or paradise, where Abraham went (Luke 16:22-25).

When King David’s son which was born out of adultery with Bathsheba was put to death by God as a judgment for the sin King David had done, King David said “I shall go to him, but he shall not return to me.” (2 Samuel 12:23) If King David was going to go to paradise when he died, he is possibly saying that in paradise he would find his baby son.

Other than this one obscure verse which is only a possible hint at where the baby went, God has not chosen to tell us what happens to babies when they die. It seems probable that they will go to a place of comfort, but we must believe that God will do what is right.

I hope this helps.
