“He called a little child to him, and placed the child among them. 3 And he said: “Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. 4 Therefore, whoever takes the lowly position of this child is the greatest in the kingdom of heaven. ” (Matt 18:2-4)
In Matthew 18:2 Jesus says that we must “become as little children” in order to enter the kingdom of God. The context of Jesus’ statement is the disciples’ question, “Who, then, is the greatest in the kingdom of heaven?” (verse 1). This is the response.
So, as the disciples focus on what constitutes “greatness” in heaven, Jesus provides a new perspective: the way “up” is “down.” Meekness is required (cf. Matthew 5:5). Jesus exhorts the disciples (and us) to seek to possess a childlike modesty in addition to their faith. Those who willingly take the lowest position are the greatest in heaven’s eyes. A young child is destitute of ambition, pride, and haughtiness and is therefore a good example for us. Children are characteristically humble and teachable. They aren’t prone to pride or hypocrisy. Humility is a virtue rewarded by God; as James says, “Humble yourselves before the Lord, and he will lift you up” (James 4:10).
Although faith is not mentioned in Matthew 18:1–5, we know that it isn’t just humility that ushers a person into heaven; it is faith in the Son of God. A humble, unpretentious faith could rightly be called a “childlike faith.” When Jesus wanted to bless the children, He said, “Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. Truly I tell you, anyone who will not receive the kingdom of God like a little child will never enter it” (Mark 10:14–15). How does a child receive a gift? With openness, honesty, and unbridled joy.
That type of happy authenticity should be a hallmark of our faith as we receive God’s gift in Christ.
Of course, children are easily fooled and led astray. In their artlessness they tend to miss the truth and be drawn to myths and fantasies. But that is not what is meant by having a childlike faith. Jesus promoted a humble, honest faith in God, and He used the innocence of a child as an example. Emulating the faith of children, we should simply take God at His Word. As children trust their earthly fathers, we should trust that our “Father in heaven [will] give good gifts to those who ask him” (Matthew 7:11).
C.S.Lewis has a wonderful passage on the “faith of children”:
“Critics who treat ‘adult’ as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But to carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.”
