2nd Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
As a general rule, God leaves the use of brute force for last, only after every other tool of entreaty has been utterly exhausted. This is one of the reasons why in so many instances, folks find that He is taking too long to execute vengeance on evil doers, and it is because of His mercy and longsuffering, why men often presume to go further in transgression, and cruelty. This does not mean that justice must not be served when it is due.
What God is saying is that when we take it upon ourselves to mete out vengeance, He is left out of the picture, and in very many instances, the retribution man inflicts goes overboard, and will do more damage than is due, or warranted. The word revenge means to retaliate, punish, or do harm to a person, group, or nation, for wrongs that have been committed against the entity in question, whether these wrongs are real or perceived.
Folks in our day are to exercise great caution and self control lest the spirit of revenge, and the thirst for blood be the rule, rather than the exception. When folks indulge in the spirit of retaliation, their minds will become darkened with evil thoughts, and if the thirst for revenge is not surrendered, a person can go completely mad in the most literal sense and in the process, they could lose touch with rational thought and will often say and do things that never would have been done and said under different circumstances.
Ecclesiastes 8: 11 Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.
May The Lord add His blessing to the study of His word. God bless!
