When missionary John Paton was translating the Scripture for the South Sea islanders, he was unable to find a word in their vocabulary for the concept of believing, trusting, or having faith. He had no idea how he would convey that to them. One day while he was in his hut translating, a native came running up the stairs into Paton's study and flopped in a chair, exhausted. He said to Paton,
It's so good to rest my whole weight in this chair.
John Paton had his word: Faith is resting your whole weight on God. That word went into the translation of their New Testament and helped bring that civilization of natives to Christ. Believing is putting your whole weight on God. If God said it, then it's true, and we're to believe it.
