What does the Bible say about infants and salvation?

In Luke 18:15-17, Jesus explicitly states, 'Suffer little children to come unto me, and forbid them not; for of such is the kingdom of God.' This emphasizes that infants and small children exemplify the total dependence on God's grace necessary for salvation. The child must be brought by another, as they are helpless, which parallels humanity's need for divine intervention to attain salvation. This aligns with the Reformed perspective that all aspects of salvation are initiated and completed by God, showcasing His mercy upon those who cannot save themselves.
