“You have wearied the LORD with your words. Yet you say, Wherein have we wearied him? When you say, every one that does evil is good in the sight of the LORD, and he delights in them; or, Where is the God of judgment?” (v.17)
The people of God in Malachi’s day were depressed and discouraged because it seemed like the wicked prospered and had it better than the godly. This filled them with doubt and unbelief, and they grumbled that everyone who does evil is good in the sight of the LORD. When they compared themselves with others, they thought it was unjust of God to bless others and not them. Not a good thing to vocalize, for God is offended when people accuse Him of injustice.
Nevertheless their question, "Where is the judgment of God," shows that they don’t understand what the God of justice would give to them. This kind of ignorant, unbelieving talk from God’s people is wearisome to Him. It shows how much His people resist His truth and His work.
One should never make the mistake that God favors the wicked and has no respect for those that serve Him (as was done by the people and priests of Malachi’s day), least you fall into the trap of thinking, "He is not going to mete our justice." As Solomon warned, “Because the sentence against an evil deed is not executed quickly, therefore the hearts of the sons of men among them are given fully to do evil.” (Eccl.8:11)
Getting away with evil for the moment doesn't mean that judgment will not be served. Some wrongs are not discovered by men, but nothing misses the eyes of Him with whom we are to stand before. Where is the God of judgment? He is coming, and sooner than you think.
The Truth: “Behold, the Lord comes with ten thousands of His saints, to execute judgment on all, to convict all who are ungodly among them of all their ungodly deeds which they have committed in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him.”
