David said to Nathan, "I have sinned against the LORD."

And Nathan said to David, "The LORD also has put away your sin; you shall not die. However, because by this deed you have given great occasion to the enemies of the LORD to blaspheme, the child also who is born to you shall surely die." Then Nathan departed to his house.

And the LORD struck the child that Uriah's wife bore to David, and it became ill.

David therefore pleaded with God for the child, and David fasted and went in and lay all night on the ground. So the elders of his house arose and went to him, to raise him up from the ground. But he would not, nor did he eat food with them. Then on the seventh day it came to pass that the child died. And the servants of David were afraid to tell him that the child was dead. For they said, "Indeed, while the child was alive, we spoke to him, and he would not heed our voice. How can we tell him that the child is dead? He may do some harm!"

When David saw that his servants were whispering, David perceived that the child was dead. Therefore David said to his servants, "Is the child dead?"

And they said, "He is dead."

So David arose from the ground, washed and anointed himself, and changed his clothes; and he went into the house of the LORD and worshiped. Then he went to his own house; and when he requested, they set food before him, and he ate. Then his servants said to him, "What is this that you have done? You fasted and wept for the child while he was alive, but when the child died, you arose and ate food."

And he said, "While the child was alive, I fasted and wept; for I said, "Who can tell whether the LORD will be gracious to me, that the child may live?' But now he is dead; why should I fast? Can I bring him back again? I shall go to him, but he shall not return to me."

2 Samuel 12:13-23

David presumed the salvation of his infant child.

At that time the disciples came to Jesus, saying, "Who then is greatest in the kingdom of heaven?"

Then Jesus called a little child to Him, set him in the midst of them, and said, "Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven. Whoever receives one little child like this in My name receives Me.

"Whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea. Woe to the world because of offenses! For offenses must come, but woe to that man by whom the offense comes!

"If your hand or foot causes you to sin, cut it off and cast it from you. It is better for you to enter into life lame or maimed, rather than having two hands or two feet, to be cast into the everlasting fire. And if your eye causes you to sin, pluck it out and cast it from you. It is better for you to enter into life with one eye, rather than having two eyes, to be cast into hell fire.

"Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven. For the Son of Man has come to save that which was lost.

"What do you think? If a man has a hundred sheep, and one of them goes astray, does he not leave the ninety-nine and go to the mountains to seek the one that is straying? And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray. Even so it is not the will of your Father who is in heaven that one of these little ones should perish."

Matthew 18:1-14

This was a covenant child that Jesus presented to them. He was a paidion - a young child, a little boy or girl, an infant. It's the same word used of Jesus in Matthew 2 when the magi visited and when Herod sent out his soldiers to kill all the male children two years old and younger.

Jesus said that this little child had been lost, having been conceived in sin, and converted. Jesus had come to save this little child. Jesus said, "one of these little ones who believe in Me", so this little one had believed in Jesus. The child had been humbled and was great in the Kingdom.

Jesus did not say that all little children were already saved or did not need converting. He did stress that the disciples need converting! They needed to continue being humbled and live a life of repentance.

We must receive these tiny covenanters. Christ made it clear that He did not approve of any disdain toward His little children.

For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy.

1 Corinthians 7:14

But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.

Hebrews 11:6
