Matthew 16:13 & 14

The gospel is defined - absolute. It is the message of the death, burial, and resurrection of Christ and the benefits it gives us - believers.

Therefore, your perception of God or saying that everyone can define God as they see fit (based on their own perception) cannot be true as God is not the author of confusion.

God calls you what he calls you in spite of your conduct because He believes that what He says will come to pass.
