How do we know children can receive grace according to Scripture?

The belief in the capacity of children to receive grace is rooted in Jesus' words in Luke 18:16-17, where He emphasizes that the kingdom of God belongs to those who are like little children. This is not to suggest that children are sinless but rather that they can accept God's grace and mercy. The Bible does not present any evidence that children, even those who die young, are excluded from salvation. Instead, it indicates that many who die before reaching moral discernment can be confidently expected to enter God's glory, resonating with the larger theological framework of sovereign grace.
