To know Jesus
I have always thought "What does it take to get to heaven?" It came to me one day while having a conversation about mountain lion being" the other white meat." I said mountain lion was unclean and the question was "who said it's unclean". I said "God said it's unclean". This got the conversation going in another direction and finally the question "What does it take to get to heaven?" My answer was a surprise to me when I said" the only way to get to heaven is to love Jesus, and if you don't love Jesus, why would you want to go there?"
Love is based on positive knowledge. Get to know Jesus by reading your Bible and talking with Him daily.
