Your sins are blocking you from God.
But Jesus died for your sins, now you can meet God, he will pour out his spirit into you.
Imagine I were to tell you "I have a personal relationship with Jessica Alba."
Chances are you would be skeptical. "Could you introduce me to her, then?" you might ask.
So I say "Of course!" and take you to a place hung with Jessica Alba posters, full of people wearing Jessica Alba T-shirts... but no Jessica Alba.
You say to me "I thought you were going to introduce me to Jessica Alba..."
"I am," I say, "these people can help you learn about her. I've been coming here for so long I feel in my heart I know Jessica Alba personally."
Surely you would think there's something funny going on in my head- but that I do not, in fact, know Jessica Alba.
Now try to understand this is the same way nonbelievers see your claims about meeting God. If you have indeed met this god, and have a personal relationship with him, then have him drop by my place. Presumably he knows where that is. Not one of his followers, and not some vaguely described feeling- Jesus himself would do.
Just let me know how he takes his tea.
