"Porque para Dios no hay nada imposible." A direct translation would in English would be, "Because for God there isn't anything impossible." The more common rendering is, "For nothing is impossible with God."
It's very fitting that such a statement would come up in the beginning of Luke's gospel. The life of Christ and his followers there after is truly incredible, but it should not strike us as suprising when we remember that anything is possible with God. I found this statement very encouraging, especially in the slower drip situation I discussed earlier.
