It is clear from things that Jesus said that faith gives us access to benefits we cannot otherwise enjoy. Like the rest of the fruit of the Spirit, the only Source we have to the kind of faith we need if we want to change things that are not into the things that we need is the Holy Spirit.
Ask Him for faith. Be prepared to then enter the particular part of the desert where faith is needed. That is the place where you gain it. Becoming more like Jesus is not an intellectual pursuit that is achieved by study alone. You have to spend focused time in the lab also. The place where our labors begin to match our beliefs (labor-atory) is the desert. There, we learn Who Yahweh is, who He says we are, and what He declares our purposes to be.
Ask for faith. Brace up…
Then Jesus said to him, “‘If You can?’ Everything is possible to the one who believes.”
