I don't think you are as much of a Calvinist as you let on. Keep obeying His commandments, Hammster. You know deep inside that keeping His commandments is required of us. Don't let anyone else tell you differently; don't let them deceive you with empty words, and do not be partakers with them.
Ephesians 5
5 For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God.
6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.
7 Therefore do not be partakers with them.
