In Matthew chapter 17 we have the facts given regarding the Lord Jesus Christ being upon the Mount of Transfiguration, and of his disciples having a faint and momentary glimpse of his glory. In the two following chapters we read of his dealings with little children. This was an example of his condescension and his rich and full grace.
Whilst his disciples were disputing about who should be the greatest among them, Jesus set before them a lesson in so practical a way that they could not easily forget. "And Jesus called a little child unto him, and set him in the midst of them, and said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven." (Matt. 18:2,3)
Now, what are the characteristics of a little child? Weakness, meekness, timidity, self-distrust, need. And these are the features of the child in grace, as well as the child in nature. Moreover, there is a gracious promise with respect to such, "All thy children shall be taught of the Lord, and great shall be the peace of thy children." (Isa. 54:13) Furthermore, as the saying goes: "Once a man, twice a child." The older the Christian grows, and the longer he is in the school of Christ, the greater his simplicity, teachableness, and sense of need of continuous help from above. The longer he lives, the more he proves the truth of Jesus' words, "Without me ye can do nothing." (John 15:5)
"Quiet, Lord, my froward heart,
Make me teachable and mild,
Upright, simple, free from art,
Make me as a weaned child;
From distrust and envy free,
Pleas'd with all that pleases Thee!"
