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).
Murmuring is a grievous sin harmful to everyone involved or impacted. When God’s people murmur, they do so because their heart is not sufficiently focused upon the Lord. Various forms of the word murmur occur forty times in the word of God. Interestingly, the number forty throughout scripture is frequently connected to a time of testing or trial. The vast majority of these occurrences reflect people who were displeased with something the Lord was responsible for doing. Their displeasure with the Lord caused them to voice their frustrations to others. Murmuring generally manifests itself outwardly, but at its root is a heart problem (Matthew 12:34; Matthew 15:19). It comes as no surprise that the medical community uses the term murmur to describe a heart problem.
