It is mine to avenge; I will repay. In due time their foot will slip; their day of disaster is near and their doom rushes upon them. - Deut 32:35 I have heard it said by god hater atheists/agnostics that they cannot believe in a egocentric genocidal God of the Bible who kills men, women and children. But then again if you asked them if there was a group of people capturing, torturing and murdering their own children and family members and other innocent people they did not like, would they not deem it just to bring those bloodthirsty people to justice? And give them what they deserved, equal punishment for equal crime?
Now we humans live in an imperfect world and we cannot see or know all the intents of the heart. So when humans administer justice we tend to either do it unjustly or err on the side of leniency because of our fear of being wrong or inability to know a persons future actions of either continuation in evil or reformation. We are not all knowing.
But not so with God. You see it's not egocentric as in a bad thing, when the center and foundation of all that exists demands that we recognize him for who he is. If I buy a pet dog and love it and care for it, it is not egocentric to demand that the dog love me and respect me as its master and owner. If it constantly runs off and seeks the affections of others or its own pleasures I would naturally go try to fetch it and discipline it to teach it proper honor. If the dog refuses my affections and love and hates me and bites me, I will take it and have it put to death, because what worth is there in a possession that brings me misery and pain and has proven it is reprobate beyond repair? Even more so with the just and true God. God created every living thing and for a purpose. If we who are given free will, to choose or reject God and choose to hate him, "bite" at him, run from him, and never submit to his corrections to reform and love him what good are we to him? After all we are a creature created by him and FOR him. The very living cells in us function and are alive because of the power of Jesus Christ who sustains all things! At any moment all he needs to do is say "enough" and withhold his providential giving of life and breath to you or me and we die. These ignorant agnostics think too much of themselves; and their own pride to be the ruler of their own lives has blinded them. Yet for us who are submitted to God in Christ, we are to love them and teach them the truths of God as kindly as we can, that he created them for himself in love not hate, and if we hate and disobey him we will suffer justice at some point.
If God ends someone's life here it is never unjust. Does not a Potter who is molding clay have the right to smash his creation and start over if it does not reflect what he is creating it to be? For man to say that God is unjust in wiping out even the entire earth and all that is in it, including every man, woman and child, the potter has to right to rework his creations. It's not wrong nor unjust. It's only wrong for one of his creations to object to anything he is doing. This goes for all his creatures... Whether in submission or not. He is true to his word, so those who are submitted to him can rest assured that all that God is doing in their lives, even painful things, are for our ultimate good according to his will.
In my reading in Revelation 8 I once again see this word picture of our prayers wafting before God. It says in vs 4-5, " And the smoke of the incense, with the prayers of the saints, went up before God out of the angel’s hand. Then the angel took the censer and filled it with the fire of the altar, and threw it to the earth; and there followed peals of thunder and sounds and flashes of lightning and an earthquake."
God relates to us the sweet incense of our prayers to him....and in context here we are seeing Gods Judgment being dealt out in response to the prayers of his saints. You see, while we are to love our enemies and pray for them, we also are called to value and love justice and goodness and pray for just vengeance from God to all who continue to do evil.
In Rev 6:10-11 we see the prayers of the slain Saints being heard. " And they cried out with a loud voice, saying, “How long, O Lord, holy and true, will You refrain from judging and avenging our blood on those who dwell on the earth?” And there was given to each of them a white robe; and they were told that they should rest for a little while longer, until the number of their fellow servants and their brethren who were to be killed even as they had been, would be completed also." God says vengeance is his...and he will avenge all injustice among his creatures. He is Holy and True.
Yet the word pictures given us here is that God is breathing deeply of the prayers of his people to avenge the injustices among us. Notice what happens immediately after breathing our prayers in Rev 8:5. In our prayers for us to better love our enemies and serve them, we must not shy away from praying for the justice of God to come upon all who continue in sin. It is okay to pray for evil ones to be vanquished by God's mighty hand, but just not our role to take that vengeance into our own hands. God has created for mankind the institution of Government to deal with evil and gave them the power of the "sword", which means death if so needed. So for us now we must pray for evil ones to come to repentance and faith, or justice to be dealt out on them, and serve them in love hoping that even they will come to know the life changing love in Christ Dfaith Jesus we have found. But by the grace of God there we all would be. God hears and will respond in due time. In the end God will make all things right.
He has showed you, O man, what is good; and what does the LORD require of you, but to do justly, and to love mercy, and to walk humbly with your God- Micah 6:8 Justice is fully interwoven along with Mercy in God't nature. Live justly and mercifully and pray for it likewise to come to all people.
So be it.
