There was once a climber, who thought he could do everything by himself. He decided to go mountain climbing one day. The mountain was higher than he thought it was, so it was getting kind of dark, until the point where he couldn't see anything. The mountain was slippery and full of snow. It was so cold.
When he was about to reach the top, his hand slipped and he fell. As he was falling, he grabbed on to the rope and he was hanging from the rope. All of a sudden, a blazing light appeared, it was God. The climber was telling God to help him. The Lord asked the climber if he believe in Him, and the climber said, “Of course, I do, so help me”. The Lord asked him again, “Do you trust me?” The climber nodded “yes”. So the Lord said : "If you do trust me, let go of the rope."
The climber looked confused, and he even held the rope tighter. Then the Lord said, “Very well”, and He disappeared. The next day, the park rangers found a climber hugging a rope two feet away from the ground.
Romans 15:13 My God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.
