"Lo, children are an heritage of the LORD: and the fruit of the womb is his reward. As arrows are in the hand of a mighty man; so are children of the youth. Happy is the man that hath his quiver full of them: they shall not be ashamed, but they shall speak with the enemies in the gate." (Psalms 127:3-5)
(Matthew 18:1-2) I can't help but picture Jesus with a smile on His face, calming the child's fears as He picked the little one up or guided him/her to the middle of the crowd. They were a joy for Him to see as he went about with His work on this earth.
