i too had that thought many times. I prayed that if ever i was in that spot that Jesus would help me. I belive that Jesus answered me. that if Jesus ever lets be me be in that situation, he will give enough faith to do his will. Jesus will always provided for those who look to him. He gives us what we need each today. He didnt tell the dicisples the whole story from start to finish in one day, but gave them what they needed (or could handle) for each day. The same is true for us. Just believe, take him at his word....
Thank you!
