A favorite story of mine is of a pastor (I think it was CS Lewis, but I can’t find the actual quote anywhere) who was asked about how he handles people with “wrong theology.” He simply said, “I have wrong theology. I just don’t know which parts are wrong and which parts are right.”
I don’t say this to imply that we should all believe in relativism. Far from it. The basic gospel remains true no matter what (that Christ died for our sins and accepting Him as Lord and Savior is the only way to be forgiven and accepted into Heaven).
The reason I love this story is because it undermines the petty discord that can creep up in churches and between different denominations. I believe it is a very good thing to research different theological viewpoints (predestination, creation, end times, etc.) but understand that some things are simply beyond our ability to grasp 100%. We must maintain a certain humility and loving attitude towards others or else we miss the whole point of the Gospel. What good is it to convince someone that your views on creation are the absolute truth only to leave them hurt and offended?
Remember that we are all wrong about something. As long as we have the Gospel right, that’s all that really matters.
