Someone I know recently died from lung cancer. She was 50 years old. Apparently, her brother, who is from NCC [New Creation Church], was fervently praying for her to be healed right up to the moment she drew her last gasp of air, refusing to let go of the hope that she would be miraculously healed after two years of fighting the disease. Her 15 year old daughter is now very angry with God for not answering their prayers. Her husband, who is a new Christian, is very confused. Her brother feels very guilty that he did not have "enough faith" to save her.
That's the problem with wrong theology. Theology is not just about dry doctrinal disputes - it makes a huge difference in how you live your life, how you die (me? I would like to have it said - God willing - that I died with a smile on my face), and how you relate to God.
Doctrine has implications, and false doctrines has consequences, some serious. We get angry with false doctrines and false teachers not because we love to argue and be right, but because false doctrines have consequences in real life. In this case, the false doctrine promoted by NCC could very well lead to people apostatizing from the faith. These people are taught that God will always heal, and when the inevitable comes when God does not heal as they have been taught he would always do so, their faith is shaken and may be shattered beyond repair. If they apostatized from the faith, they would be hardened against the Gospel message because they have "Been there, Done that". They would have "tried" the faith, but reality in their experience has shown "Christianity" to be false, or at least their version of Christianity which the false teacher has taught them, and who is there to tell them the difference?
The role of a watchman is a thankless task. The haters (AODMers) continue in their mocking, yet they show their hatred by preferring souls to be led astray instead of false teachers to be named and marked. They love the wolves and not the sheep. In this case, they would rather people lose their faith and be hardened against the Gospel rather than Joseph Prince to be called a false prophet and teacher. Of course, seeing their hatred for the flock, they would probably be wolves themselves who love nothing than for the flock to follow and adore them instead of Christ.
So what should we do with those who follow these false prophets? We should warn them. They may very well hate us (since men love darkness rather than light), but we may impress the truth upon them so that when such a crisis come, they would hopefully come to see the light as God may use the situation to bring them to Himself. When the "theology" taught by the false teachers do not work (which they will not), we hope that they would recall their anger at our warnings and in desperation seriously think through the issue according to Scripture. For who knows whether God will use such a situation to bring them to their senses?
