Markus 10:14

10:14 But when Jesus saw this, he was indignant and said to them, “Let the little children come to me and do not try to stop them, for the kingdom of God belongs to such as these. ¹ 

Markus 16:14

16:14 Then he appeared to the eleven themselves, while they were eating, and he rebuked them for their unbelief and hardness of heart, because they did not believe those who had seen him resurrected.

[10:14]  ¹ sn The kingdom of God belongs to such as these. Children are a picture of those whose simple trust illustrates what faith is all about. The remark illustrates how everyone is important to God, even those whom others regard as insignificant.
