By hearing the gospel, and choosing to believe it.
Deut 30:
19) I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:
Calvinists take being "dead" too far.
ALL of us fall short.
If God literally did that, then He is duplicitous and cannot be trusted, nor can we trust the Bible.
1 Tim 2:
4) Who will have all men to be saved, and to come unto the knowledge of the truth.
2 Pet 3:
9) The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Eze 33:
11) Say unto them, As I live, saith the Lord GOD, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?
I know most of the verses Calvinists use to support their doctrine...
