Religious relativism is a self defeating view, the idea that there is no objective truth is an objective truth claim. The religions and beliefs of this world are diverse and contradictory. We should search for truth through our experience of the world around us and based on what we can know.

Pain and suffering is an unavoidable part of the world that we live in. Much of the pain and suffering in this world is a result of human choices, which is a consequence of the free will that God gave us. Some pain and suffering are consequences of us living in a fallen world; there isn't always a clear reason for the suffering we endure, but we know God can use it for good and can show us things through our pain.

The Bible stands out from other scriptures in its accuracy of historical claims, and it's fulfilled prophecy. God chose to confirm His message to mankind through these verifiable claims. Some spiritual texts contradict history, while others make no verifiable claims.
