Do not take revenge, my friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,” says the Lord. - Romans 12:19 NIV
God delivers justice in different ways. Sometimes it’s through routine personal (and peaceful) interaction. Other times normal office procedures result in a just solution. Some actions require the involvement of the police or the courts. And sometimes justice will not be revealed until after our deaths, but recognize that God sees an eternal picture that we cannot comprehend while wrapped up in our temporal, earthly matters.
In every case, know this: God will bring about justice. Maybe it won’t be as dramatic as a vain man getting his hair stuck in a tree. But in the end, God’s justice will most certainly be done.
