Giving God a chance
When you believe, you had come to believe first and that process meant swiping your mind clean of your prejudices towards God and giving Him a chance. It's saying, Ok, God, so far I don't like what I see or hear, but I am willing to put aside all I have heard about You and am willing to get to know You personally. I am willing to give You a chance. And the reason I am willing to do this is so that I can make up my own mind about You about the purpose of my life about heaven and hell about what happens to my soul when I die about the possibility of purity and innocence and true love and the possibility of eternal life and happiness, and about my specific calling on earth. I don't want to live for myself anymore, but for Your calling on my life. You have called me, here I am! And I trust, once I do on earth what I was made for, I will be happy and live eternally.
