Only twice in the Bible does an animal talk - the voice of Satan coming from the serpent in the Garden of Eden and the voice of God coming from the talking donkey in Numbers. The great Gentile Prophet Balaam proves less godly than his donkey when Balaam proves blind to the angel in his path but the donkey sees the angel. The angel is there to stop Balaam from doing a great evil. Later, Balaam reverses course and speaks of his faith in God. But even later, he waffles again, turning away from his faith. That is how we live, our faith gaining and waning throughout our lives - and we must always be prepared to spot the angel standing in our path, warning us.
