you have to realize that it sounds a little outrageous to say that your faith is right, and everyone else is wrong.
Sounds rather relativistic to me. How many truths can there be? If you say that there is more than one truth, then what if my truth says that your truth is false? Obviously your truth says that my truth is false, so it must work both ways. So whose truth is the true truth?
Perhaps you're saying "There are no absolutes and no truth. That's why it's outrageous for you to say you've got truth".
Is that true that there are no truths? Is it absolutely true that there are no absolutes?
Is nobody right? If you're right about nobody being right, well, then you're wrong about nobody being right!
I'm sorry. That just doesn't work. In order for there to be truth, it has to be universal, absolute and exclusive. Ther can be only one truth. And God's word is true. "Sanctify them through thy truth: thy word is truth." (John 7:17)
