How do you determine what you believe? Does it come from inside you or from some outside source? Feelings seem to outweigh everything in today's world. This can create a fairly convenient religion. Keep the parts of the Bible you like, and throw away the rest. Christianity is a doctrinal faith, based on the doctrines of the Bible—God's Word. To be a Christian means learning those doctrines. Truth comes from God, and that is where we must start in our spiritual journey.
