The Scriptures seem pretty clear to me on how infants are regarded in the eyes of God. Take a look at Israel, for instance, even though most of the Israelites were destroyed in the wilderness for disobeying the commandments of God (1 Corinthians 10:5), the infants were spared and allowed to enter the promised land and take possession of it. Why did God do this?
And the little ones that you said would be taken captive, your children who do not yet know good from bad--they will enter the land. I will give it to them and they will take possession of it. Deuteronomy 1:39
God allowed the babies to inherit the promised land because they did not yet have the knowledge between good and evil. In other words, were innocent before God. This is reason that God commands each and everyone to be like little children, otherwise, we too, will not enter the promised land.
And he said: "Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. Matthew 18:3
Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults. 1 Corinthians 14:20
Remember, the Kingdom of God belong to little children and ones like them.
