Indisputably, there are Scriptural cases to be made regarding all major doctrinal views for salvation. Some of these views appear to be mutually exclusive (e.g. Calvinism and Armenianism.) I think this renders the Bible self-contradictory on the basic matters of how salvation works.
Christians, can you explain to me how you believe salvation works, and how you know your beliefs on salvation are correct, based on the Bible?
