A. This is an important question, and deserves a more complete answer than room will allow here. I suggest that you read the article The Calvinist vs. Arminian Debate found in the Articles section on this site. This article will give you the differences between these two interpretations of the sovereignty of God, and will explain why I am an Arminian. It will also reveal that every believer can have eternal security, but that the doctrine often referred to as “once saved, always saved” is really outside both the Calvinist (Reformed) and Arminian theological positions.
