The Milk of the Word.
This subject divides itself into three parts:
I. Healthy appetite, or, in other words, an earnest desire for spiritual nourishment: "As new-born babes, desire" earnestly, covet eagerly, "the sincere milk of the word."
II. Healthy food, or, in other words, God's truth as contained in Holy Writ: "Desire the sincere milk of the word." The milk of the word, or, according to a better translation, rational milk, the sincere milk, i.e.,milk free from all deleterious admixtures.
III. Healthy growth: "that ye may grow thereby unto salvation." Growth unto salvation implies (1) growth in knowledge, (2) growth in holiness.
