Charles H. Spurgeon on Psalms 119:11

Thy word have I hid in mine heart. There is great difference between Christians and worldlings. The worldling hath his treasures in jewels without him; the Christian hath them within. Neither indeed is there any receptacle wherein to receive and keep the word of consolation but the heart only. If thou have it in thy mouth only, it shall be taken from thee; if thou have it in thy book only, Thou shalt miss it when thou hast most to do with it; but if thou lay it up in thy heart, as Mary did the words of the angel, no enemy shall ever be able to take it from thee, and thou shalt find it's comfortable treasure in time of thy need. William Cowper.
