1. Total Depravity: to mean that any man in his natural state is incapable on able to do anything to please or gain merit from God. When man is totally depraved he cannot discern the truth of the gospel understand it when it is presented to him. The Calvin disqualifies the meaning of "free will", indicating that man is not totally free, but is able to respond to God because of election and irresistible grace.
2. Calvinists believe a man obtain salvation because God began the process by choosing. Without any outside influence. The ground of election is a God himself, which is to say salvation begins in God's will and purpose and not in an act of faith or some other condition and responder. As a result man has no part in it.
3. Limited Atonement: if man is totally depraved so that he cannot respond, and God is sovereign in His unconditional choice, and when Jesus died, He died for those that were chosen by God.
4. Irresistible Grace: Calvinists teach that the grace of God is as immutable as the power of God so that man cannot resist it. They teach that since God of his own free will has chosen (elected) man and Christ has died for him, then man cannot resist the power of God that brings him to salvation.
5. Perseverance of the Saints: they teach that the Saints will persevere because this patient is dependent upon God's irresistible grace which was granted to them because Christ died in atonement limited to the elect. They also teach distance man has absolutely nothing to do with his salvation, he will persevere Because the Savior declared that he has eternal life.
