Why did Billy say a prayer just before he left for home? Also, what did he mean when he said “My second prayer wasn’t just said with words”?

Billy says a prayer and asks God to help him. Just when he thinks all hope is lost, Billy gets an idea. He takes the handle off of his lantern, stretches it out, and bends the end so that it forms a hook. He checks to see how deep the water is by the bank. It is only 18 inches - he can make it. He takes off his clothes, wades into the water, and makes his way out to Little Ann. When the water is finally up to his chin and he can go no further, he starts to "fish" for Little Ann's collar with the lantern handle. He eventually hooks it and pulls her out of the water. Billy starts to make his way back out of the water, but it is difficult because his whole body is numb. When he finally makes it out of the water, he dresses and builds a big fire. He and Old Dan revive Little Ann, as the cold water froze her body into a temporary state of paralysis. Billy feels good and knows she will live. I think really meant his prayers . He says of his second prayer, All of my heart and soul was in it.
