Paul warns such debates only prove to destroy, not only participants but onlookers (2 Timothy 2:14). The doubt infested by empty debate spreads like a cancer causing individuals to lose faith. We must resist the temptation to join in the fray. If someone is asking us an honest question, we gladly share with them the truth. But if the goal is merely debate, we avoid getting entangled in the trap.
Rather, we study God's Word so that we rightly understand what scripture is teaching. Then when we share with others, we will be sharing life, not death (2 Timothy 2:14-18).
