Spurgeon on Spiritual Babies and Spiritual Adults.

Among those who fear the LORD there are little and great. Some are babes, and others are giants. But these are all blessed. Little faith is blessed faith. Trembling hope is blessed hope. Every grace of the Holy Spirit, even though it be only in the bud, bears a blessing within it. Moreover, the LORD Jesus bought both the small and the great with the same precious blood, and He has engaged to preserve the lambs as well as the full-grown sheep. No mother overlooks her child because it is little; nay, the smaller it is, the more tenderly does she nurse it. If there be any preference with the LORD, He does not arrange them as "great and small" but as "small and great."  -Charles H Spurgeon
