There is a direct correlation between your beliefs regarding future events and the way in which you can handle the hurts that others have inflicted upon you. Here’s what I mean. If you believe that God is the future judge of the world and will right all wrongs in the end, then, you will be able to free yourself from anger and the need to seek revenge. You will trust the Lord, who said, “Vengeance is Mine. I will repay” (Romans 12:19).
However, if you believe that God will forgive everybody in the end, then you will have great difficulty putting aside the wrongs done to you. Your heart will continue in hardness toward those who hurt you. You will (rightfully) be angry and will (rightfully) desire for justice to prevail.
In other words (using the words of a friend), “Soft eschatology will make hard people and hard eschatology will make soft people.”
