As I said, I've only slowly come around to the Reformed tradition. It's taken years of reading different texts, working through heavy issues in metaphysics, thinking deeply through implications of the Creator/creature distinction, and coming to appreciate the Reformed tradition beyond its soteriology. I was brought into its richer tradition of spirituality through an appreciation of its emphasis on a constellation of biblical doctrines like revelation, union with Christ, providence, the atonement, and the Lord's Supper, which form the proper background for its teaching on election.
That process didn't happen in a vacuum, though. A couple patient buddies embodied helpful humility toward me as I worked through the issues. They were quick to celebrate the truths we shared together. They argued graciously with me at the right times but never questioned my faith or intelligence. They pointed me to good resources and were willing to read some of the ones to which I pointed them. Essentially they took the time to hear and understand my problems as we discussed. More than that, they honestly tried to extend the free grace that they believed they'd received from God through no merit of their own. ...
Let me put it this way: if you're really a Calvinist and believe you've received knowledge of the truth by the sheer grace of God, which is what a Reformed view of knowledge teaches, then be patient with those who don't see it. God has been (and is currently being) patient with you in some area as well. So stop sneering and ask God to humble you enough to be helpful to those offended at or wrestling with those doctrines you now hold dear.
