What he has created.

Understanding that everything is created by him (God), and for him (God), is key in embracing the unique ways that God uses all things for the good of those who love him. If God wants to use a donkey, a raven, a prophet, or an angel to accomplish his work of salvation and the glorification of his Son, we must humbly respect and rejoice in that. In sight of the totality of God's majesty we are just part of that grand plan, and the angels also play an important part. God's total sovereignty is our focus, and not swearing by, or exalting above, but respecting his creative hand and everything in his creation can help in the uniqueness of -how he holds "everything" together. Colossians 1:15-23
