Thank you to everyone who replied. I have been becoming much stronger in the doctrines of grace over the past few months. Though I have believed it for four years, I have found lately there are times when I clung unknowingly to my old beliefs. My question arose from my parents who questioned my wife's salvation because she could not give a powerful and precise moment of salvation. This bothered me as my father is a pastor and has been calvinistic for two decades. Another thank you to Pilgrim and Wes, your words were most helpful.
