Children
It seems significant that Three of the Gospels record Jesus care for children stating "to such belongs the kingdom of heaven."

Matthew 19:13-14 | Let the Children Come to Me Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people, but Jesus said, “Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.”
Mark 10:13-16 | And they were bringing children to him that he might touch them, and the disciples rebuked them. But when Jesus saw it, he was indignant and said to them, “Let the children come to me; do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.” And he took them in his arms and blessed them, laying his hands on them.
Luke 18: 15-16 | Now they were bringing even infants to him that he might touch them. And when the disciples saw it, they rebuked them. But Jesus called them to him, saying, “Let the children come to me, and do not hinder them, for to such belongs the kingdom of God.

In his book Safe in the arms of God, MacArthur uses Revelation 7:9 as evidence that babies and children go to heaven, for how else could every tribe, tongue, and nation be represented in Heaven if not all have heard to gospel. Revelation 7:9 After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands,

2 Samuel 12:16-23 | David therefore sought God on behalf of the child. And David fasted and went in and lay all night on the ground. And the elders of his house stood beside him, to raise him from the ground, but he would not, nor did he eat food with them. On the seventh day the child died. And the servants of David were afraid to tell him that the child was dead, for they said, “Behold, while the child was yet alive, we spoke to him, and he did not listen to us. How then can we say to him the child is dead? He may do himself some harm.” But when David saw that his servants were whispering together, David understood that the child was dead. And David said to his servants, “Is the child dead?” They said, “He is dead.” Then David arose from the earth and washed and anointed himself and changed his clothes. And he went into the house of the Lord and worshiped. He then went to his own house. And when he asked, they set food before him, and he ate. Then his servants said to him, “What is this thing 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.” He said, “While the child was still alive, I fasted and wept, for I said, ‘Who knows 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 will not return to me.”
I shall go to him
God chose to take a child (perhaps an early adult) from this world to save him from God's punishment on the house of Jeroboam because he found something pleasing in the boy.
1 Kings 14:13 | And all Israel shall mourn for him and bury him, for he only of Jeroboam shall come to the grave, because in him there is found something pleasing to the Lord, the God of Israel, in the house of Jeroboam.
