S – Truly I tell you, whoever does not receive^, the kingdom of God like a little child will never enter it.” ¹⁶ After taking them in his arms, he laid his hands on them and blessed them. 

Mark 10:15–16 CSB

O – Commentary: 

Whoever will not receive God’s kingdom as a gift now with the trustful attitude of a child will never (emphatic negative, ou mē, “by no means”) enter it. He will be excluded from its future blessings, specifically eternal life (cf. vv. 17, 23–26). God’s kingdom is not gained by human achievement or merit; it must be received as God’s gift through simple trust by those who acknowledge their inability to gain it any other way (cf. comments on 1:15).

10:16. Jesus’ loving action (cf. 9:36) vividly illustrated that His blessing is freely given to those who receive it trustingly. The intensive compound verb blessed (kateulogei, imperf., occurring only here in the NT) emphasizes the warmhearted fervor with which Jesus blessed each child who came to Him.

“Mark,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A – I love how Jesus used a child as the illustration and blessed the children.  It is a great picture for us to recognize the simplicity of knowing Christ and the importance of our faith.  We can make it harder than it needs to be.  Also, he reminds us to bless our own children. We have every ability to do that today.

R – Heavenly Father, you are unlimited in power and mercy.  Remind us what you desire most in our relationship with you.  Empower us to focus on the fundamentals of our relationship.  We are grateful for the blessings you give us each day.
