Calvinists are very evangelical because the way God saves his elect is through the spreading of the Gospel. If you do not spread the truth, nobody can be saved.
Let me get this important doctrine straight. I can't accept Christ (and let Him work His salvation for me) because my 'will' in accepting Him would somehow taint God's power. BUT if I (and other reprobates like me) disobediently refuse to "... spread the truth, nobody can be saved."
That's what's wrong with Calvinism. The drawing power of love to accept Christ is 'too weak' and man-like and it taints God's power (so they say), but the driving necessity of 'obedience' is just necessary cooperation. Talk about turning the Gospel of Christ on its head. The Pharisees and the Sadducees were also long on 'obedience' and short on 'love.'
I'll take Jesus, thank you.
