[JamesP81]

You are incapable of "accepting Jesus" until He calls for you.

I would add something to this. While only God can call on the hearts of men, the Bible also says 'knock, and it shall be opened to you.' If you wish to be called by God, simply ask Him. You might be surprised by the results.

Long ago, when I wasnt in faith, I remember clearly praying “God, if you do exist, if you are there, show yourself to me. Let me know you are there”.

I don’t believe that anyone can make a prayer lke that, and really mean it, and not have it answered.
