Luke 9:50

9:50 But Jesus said to him, “Do not stop him, for whoever is not against you is for you.”

Luke 18:16

18:16 But Jesus called for the children, ¹  saying, “Let the little children come to me and do not try to stop them, for the kingdom of God ²  belongs to such as these. ³ 

[18:16]  ¹ tn Grk “summoned them”; the referent (the children) has been specified in the translation for clarity.

[18:16]  ² sn The kingdom of God is a major theme of Jesus. It is a realm in which Jesus rules and to which those who trust him belong. See Luke 6:20; 11:20; 17:20-21.

[18:16]  ³ 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.
