There are many places in scripture which show God using aspects of the creation for His purposes. Ps 104 also talks about God clothing Himself with the creation. A personal clothing with the creation is when God as the Word became flesh and dwelt among us in the person of Jesus Christ. He also uses physical means to give us grace (Word and Sacrament). Elihu's description of God's providential mercy and judgment through storms shows how God can act toward us, but does not show us the Gospel. For this, we rely on where God promises to us He offers life and salvation: His Word and Sacrament.
