To Calvinists: How long it takes you to believe on Jesus after you heard the gospel?

The reason I make this topic. Because Calvinism doctrine's one of the five points- 'Iresistible Grace'. It teaches that God's effectual of power with force to touch saint's heart after hear the gospel, then immediately believe in Jesus without make decision.

To all Calvinists, please be honest with my question. I cannot see your heart, only God knows you. I am sure several some of you Calvinists did fianlly believe in Jesus took a while after you hear the gospel, not just a second, or one minute either. Also, you better be admit telling me, be honest. WHY you did believed in Jesus after you heard the gospel? Please do not say to me, "Because God tolds me so." You have to admit tell the honest to us, WHY you did believe in Jesus after you heard the gospel? Please do not play with my question, ok? God is watching you.
