Trumpeting Truth

Have you ever stopped to think of what you would do if you found out that all or some of what you sincerely believe and hold to be sacred truth were not in accordance with the word and will of God? If you should find that you are in error would you change? What would you do if you found out that your church community is not in perfect obedience to the word and will of God? Would you try to find reasons and excuses to justify your stance and or say "it doesn't really matter? Would you continue to follow the doctrines of your church, which are false, or would you have the courage to change and follow the word and will of God?
