Man’s true spiritual condition is nowhere more clearly seen than in the absence of a proper submission to and reverence for God. Biblical fear for God consists of : 1) awe of His greatness and glory, and 2) dread of the results of violating that holy nature (Proverbs 9:10; 16:6; Acts 5:1-11; 1 Corinthians 11:30).
Commentary from the MacArthur study Bible, notes for Romans 3:18.
“Your words against Me are harsh,” says the Lord.
Yet you ask: “What have we spoken against You?”
You have said: “It is useless to serve God. What have we gained by keeping His requirements and walking mournfully before the Lord of Hosts? So now we consider the arrogant to be fortunate. Not only do those who commit wickedness prosper, they even test God and escape.” Malachi 3:13-15
“For indeed, the day is coming, burning like a furnace, when all the arrogant and everyone who commits wickedness will become stubble. The coming day will consume them,” says the Lord of Hosts, “not leaving them root or branches. But you who fear My name, the sun of righteousness will rise with healing in its wings, and you will go out and playfully jump like calves from the stall. You will trample the wicked, for they will be ashes under the soles of your feet on the day I am preparing,” says the Lord of Hosts.
