The apostle John writes in I John 5:4-5, "For whatever is born of God overcomes the world. And this is the victory that has overcome the world—our faith. Who is he who overcomes the world, but he who believes that Jesus is the Son of God." The honest recognition of need, the desire to glorify God, and the practice of overcoming leads a called-out one to live by faith.
Jesus Christ is the One that God has assigned to oversee and empower us. He is the Helper and Advocate (I John 2:1) who goes alongside, enabling us to be created in His image. From Him, we draw spiritual strength, and He gives grace to the humble.
