15. ἀμὴν λέγω ὑμῖν. This solemn warning, “the final lesson of His ministry in Galilee” (Swete), is omitted by Mt., who has recorded similar words Mat 18:3, but without the important δέξηται, which implies that the Kingdom is offered. “Receiving the Kingdom” means accepting the rule and sovereignty of God. “Entering the Kingdom” means becoming a member of the society in which His rule prevails. The leave to enter is always open to those who qualify themselves for entering.
ὡς παιδίον. With perfect trust, joy, and hope; “even as a weaned child” (Psa 131:2).
οὐ μὴ εἰσέλθῃ. Shall in no wise enter; cf. Mar 9:1; Mar 9:41, Mar 13:2; Mar 13:19; Mar 13:30.
