It’s not for the lazy, it’s for the self-righteous. The reason unlike other religions, Christianity was unique in that it did not say “you are godly”, or “you are the chosen one” which is something that people want to hear. Christianity says “you are a sinner”. Calvinism is just a construct so that people can think they are the chosen one and feel good about themselves.
I take it that you are not actually a Calvinist.
Calvinism is decidedly the most non-intellectual of the faiths in this world...it’s on par with Mormonism and Islam as childlike in its construction.
"Blessed is the man whom thou choosest, and causest to approach unto thee" -- Psalm 65:4
Nothing in any of us merits God's grace. It is a gift, freely given according to His will. Saved by grace through faith in Jesus Christ.
