Leviticus 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbor as thyself: I am the Lord.
When it comes to getting even with someone for an injustice done, from the Christian’s perspective this should be done only at God’s discretion, and at His direction because when it comes to handling justice, there is very often the tendency for individuals to go overboard, especially if the wrongs were done to them personally. Again, sometimes you might read in the Bible where the God-fearing individual may have adopted ways and means that may seem to be questionable to us.
And because of man’s fallen nature, some in certain instances might do the right thing the wrong way. Whenever this occurs in the Scripture, it should not cause the reader to lose sight of the bigger picture, nor should it lead us to conclude that in every single instance God approved of those methods that were adopted by the person in question. We should be very careful not to be more righteous than God.
Wherever and whenever discrepancies in judgment in ways, means and methods may seem to appear in the one whom God is using, the natural tendency is to conclude that such actions were not in harmony with Biblical teaching and principles. You may actually have a point, but if God was in it, that should be enough to settle the matter in our minds, because justice and mercy are always to be understood in the context of God’s Sovereignty over everything and everyone.
Romans 12:18 If it be possible, as much as lieth in you, live peaceably with all men. 19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
May God add His blessing to the study of His word. “Good night” and God bless!
