I believe we are doing a disservice to mankind by enacting God's will on anyone. God gave us free will to choose to love Him. Why should we force things on people? For their own good?
Throughout History people that believe to be enacting God's will have failed to do just that.
Hitler believed he was enacting God's will during The Holocaust.
A leader of the false religion of Mormonism called LDS Church named Brigham Young thought he was enacting God's will when he ordered the killings of 120 men, women and children in what is now known as the Mountain Meadows massacre. On a side note, there is a great movie called September Dawn that I highly recommend if you want to understand the false and tragic thinking of the Mormons. Chills went down my spine when they were screaming "Blood Atonement" over and over again.
Many believe the Crusades was a huge stain on our history when the Roman Catholic Church (RCC) murdered many, but they were a direct response to Islam's attacks on the innocent people believing they, the Muslims, were enacting their god's will.
Another fine example is Andrea Yates (raised Roman Catholic), who lived an hour away from me at the time, decided to drown all five of her children. She claimed "It was the seventh deadly sin. My children weren't righteous. They stumbled because I was evil. The way I was raising them, they could never be saved. They were doomed to perish in the fires of hell."
We can plainly see the pattern of people acting as God. People that are not of God, love, try to enact the will of God. This horrible misunderstanding of Scripture is what delivers them to the devil. God is God, we are not. God knows all and we do not. If a person blows up a abortion clinic they are doing the devil's work, not God's. If some joker is claiming to heal people of spinal bifida he is of the devil.
So what we need to take from this is the fact there is only one God and we are to worship Him. Any deviation and the results are horrific. Once we start reasoning ourselves we stop letting God be in charge. Let God do God's work, as we can plainly see, He is much better at it then man is. The key is that everything that is contrary to God comes from the enemy of our souls.
Proverbs 3:5-6 "Trust in the LORD with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths."
