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.
When you truly love someone, you find yourself developing a love for the things that he or she loves. It should be no different concerning our relationship with the Lord. The more love we have for the Lord, the more love we display for the things dearest to Him. This means that the closer we draw to Him, the more we will love things that He loves, like judgment (Isaiah 61:8) and righteousness (Psalm 11:7), the lost (John 3:16) and the saved (1 John 4:21), peace and truth (Zechariah 8:19). We will also have a greater love for the Jewish people (Zechariah 2:8). Perhaps a more accurate gauge by which to judge your love for the Lord is to gauge your love for the things which He loves.
