Ps 112:1

“...When ye hear sung in the Psalms, "Praise the Lord, ye children" (ver. 1); imagine not that that exhortation pertaineth not unto you, because having already passed the youth of the body, ye are either blooming in the prime of manhood, or growing gray with the honours of old age: for unto all of you the Apostle saith, "Brethren, be not children in understanding; howbeit, in malice be ye children, but in understanding be men." What malice in particular, save pride? For it is pride that, presuming in false greatness, suffereth not man to walk along the narrow path, and to enter by the narrow gate; but the child easily entereth through the narrow entrance; and thus no man, save as a child, entereth into the kingdom of heaven.”
