Matthew Henry Commentary Luke 18:15-17

"And they were bringing unto him also their babes, that he should touch them: but when the disciples saw it, they rebuked them. But Jesus called them unto him, saying, Suffer the little children to come unto me, and forbid them not: for to such belongeth the kingdom of God. Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall in no wise enter therein." — Luke 18:15-17 (ASV)

No one is too little or too young to be brought to Christ, who knows how to show kindness to those who are not capable of doing service for Him. It is the mind of Christ that little children should be brought to Him. The promise is to us and to our seed; therefore, He will bid them welcome to Him with us. And we must receive His kingdom as children, not by purchase, and must call it our Father's gift.
