Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
Psalm 119 is filled with statements promoting the necessity of the word of God. Seven times in this psalm we find a statement declaring the writer’s desire to meditate upon the words of God. Three of these times he states emphatically that he will meditate in God’s statutes or His precepts (Psalm 119:15, 48, 78). Not only was meditating upon God’s words something that the psalmist desired to do in the future, but he had formed this habit long ago (Psalm 119:23, 99). The writer of this psalm, like other successful believers in the past, made it common practice to meditate in the words of God both day and night (Psalm 119:97; Psalm 1:2; Joshua 1:8).
