There are
numerous Bible verses and
quotations from the church fathers supporting the five points of Calvinism. The doctrines of grace are simply a convenient way of articulating what’s already revealed in the Bible.
It’s only called “Calvinism” because John Calvin popularized the doctrines of grace, he did not originate them. It’s the same doctrines that Augustine taught against Pelagius and
Luther taught against Rome.
Most importantly, since Jesus is the author and finisher of our faith (Hebrews 12:2), we should look to the words of Jesus and see if they support the doctrines of grace.
Calvinism is important to me because it's supported by the Bible, and also because of its great benefits. I have never felt more loved by Jesus in my entire life, and I've never felt more secure in my salvation. I am so thankful, that it makes me want to live in love and obedience to Jesus.
To believe that Jesus chose me from before the foundation of the world, based on no merit on my part whatsoever, not even my free-willed efforts to believe or disbelieve, and that He will safely lead me to ultimate salvation and never abandon me, no matter how many times I might fall, is very liberating and also very humbling.
Here are just a few verses from the Gospels:
