Only a foolish man thinks he can hide anything from the Lord. This includes his thought life. The Lord knows all man’s thoughts (1 Chronicles 28:9) which includes the good (Malachi 3:16) and the bad (Psalm 94:11). David expressed this truth to the Lord when he said, “Thou knowest . . . my thought afar off. . . . For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether” (Psalm 139:2-4). The Lord Jesus Christ often exhibited this capability during His earthly ministry (Matthew 12:25; Luke 5:22; Luke 6:8; Luke 9:47; Luke 11:17). Even the written word of God reveals this ability by being “a discerner of the thoughts and intents of the heart” (Hebrews 4:12).
When a believer meditates upon the things of God, those truths become more firmly planted in the heart. Eventually, the contents of the heart become evident from the words that escape the mouth (Luke 6:45). Therefore, the meditations of our heart will eventually be the words of our conversations. This is exactly the truth conveyed by Asaph in our passage from Psalm 77. He understood that meditation upon the work of God would eventually cause him to talk of God’s doings. It is right for God’s people to speak truth, especially when it concerns testifying to the truth of God’s holy words. Yet, this is not possible unless a believer first hides the words of God in his heart (Psalm 119:11), and one way to do so is through meditation.
