John Calvin created the false doctrine of Calvinism which has five points that make up the acronym TULIP:
T: Total depravity: People are so depraved that they cannot even make a choice to believe the gospel (no free will).
U: Unconditional Election: God 'elected' or chose who goes to heaven and who goes to hell before the foundation of the word and people have no choice in the matter.
L: Limited Atonement: Jesus didn't die for everybody, only those that were unconditionally elected.
I: Irresistible Grace: God forces salvation on those he 'elects.'
P: Perseverance of the Saints: Those who have been elected will lead a Godly life until the end.
