I grew up in the Christian Reformed church with my family having deep Reformed roots, I moved to an area of the country which had few Reformed churches. For almost 20 years, I attended, was a member, and even a lay leader in a wide-range of churches from Assembly of God to Calvary Chapel to Baptist to a very large United Methodist church to a small nondenominational “fellowship” to “community” churches.  Some of these churches did not label their doctrine as Arminian. I was disturbed by some of the sermons, but I could not pinpoint what was wrong. Often, I thought the problem was just the particular minister.  Eventually, a friend asked me if I remembered “TULIP”, the acronym for the Five Points of Calvinism which is the most important part of Reformed Doctrine.  I began to study the differences between Calvinism and Arminianism.  I then understood that it was Arminian doctrine presented in some of these churches.  I realized Calvinism’s importance, not only for how it made me appreciate God’s grace more, but for how Calvinism is the true doctrine of salvation
