Dr. Mohler and Dr. Daniel Akin have reposted their article showing from scripture why they believe that infants go to heaven when they die.
they lay out six reasons for this belief. here is number six and an overall point about God’s justice, but do go read the whole thing. Including Charles Spurgeon in the conclusion
Sixth, some in Scripture are said to be chosen or sanctified from the womb (1 Samuel 1:8-2:21; Jeremiah 1:5; Luke 1:15). This certainly affirms the salvation of some infants and repudiates the view that only baptized babies are assured of heaven. Neither Samuel, Jeremiah or John the Baptist was baptized.
After surveying these arguments, it is important for us to remember that anyone who is saved is saved because of the grace of God, the saving work of Jesus Christ and the undeserved and unmerited regenerating work of the Holy Spirit. Like all who have ever lived, except for Jesus, infants need to be saved. Only Jesus can take away their sin, and if they are saved it is because of His sovereign grace and abounding mercy. Abraham said, “Will not the Judge of all the earth do right?” (Genesis 18:25). We can confidently say, “Yes, He will.” When it comes to those incapable of volitional, willful acts of sin, we can rest assured God will, indeed, do right. Precious little ones are the objects of His saving mercy and grace.
It is true that babies are incapable of volitional, willful acts of sin, but that is not to say that they are not sinners. We all are born in a sinful state with a sinful nature and it is that sinful nature that Jesus went to the cross for. Isaiah 48:8b: “For I knew that you would surely deal treacherously, and that from before birth you were called a rebel.” Jesus came to die for our original state of sinfulness NOT the everyday sins that we commit. He did not die for the sins that we are going to commit one day. When Adam and Eve sinned, ALL sinned for ALL time. So how, then, can an infant born with a sinful nature enter into heaven? Does that not render Jesus’ sacrifice to be irrelevant?
I’ve looked up and read the three verses that you mentioned in this article. Each verese mention babes but every single one you have taken out of contex. Babtizing is just a away to show how you have been cleansed. Its just an act. The Bible says you dont go to heaven by works but by having a relationship with him.
