"The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple. The statutes of the LORD are right, rejoicing the heart: the commandment of the LORD is pure, enlightening the eyes. The fear of the Lord is clean, enduring for ever: the judgments of the LORD are true and righteous altogether" (Psalm 19:7-9).
Most Christians spend little time in the Word of the Lord, and this is a great tragedy. It is the necessary food for health and joy in our spiritual lives. "The sincere milk of the word" (I Peter 2:2) is for "newborn babes" and the "strong meat" is for those who are not "unskillful in the word of righteousness" (Hebrews 5:12-13). "Thy words" are also "honey to my mouth" (Psalm 119:103), and "every word that proceedeth out of the mouth of the LORD" is the very bread by which "doth man live" (Deuteronomy 8:3).
Not only are the Scriptures basic in salvation (II Timothy 3:15; I Peter 1:23), but also in sanctification and cleansing day by day: "That He might sanctify and cleanse |the church| with the washing of water by the word" (Ephesians 5:26).
The Scriptures also provide daily guidance for those who will use their directions: "Thy word is a lamp unto my feet, and a light unto my path" (Psalm 119:105). Every Christian must be a seed-sowing witness for Christ, and "the seed is the word of God" (Luke 8:11). In the Christian's armor, the sole offensive weapon is "the sword of the Spirit, which is the word of God" (Ephesians 6:17), and this means a victorious life and testimony for the Christian who uses it.
The wonderful testimony of David in our text is the Old Testament equivalent of the great assertion by Paul in II Timothy 3:16: "All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness." HMM
