@Craven de Kere,
Can good come from evil. Yes. Does that mean that the evil was in some way 'good' for the world. No.
This might seem a contradiction but it is only a contradiction to someone who doesn't know God.
And leads to the question, Why does the Creed speak only of God's Omnipotence?
The Omnipotence of God the Reason for Faith and Hope
"And you will observe this attribute of God is the only one mentioned in the Creed. "I believe in God, the Father almighty." It is not said "I believe in God the Father All merciful, or All holy, or All wise," though all these attributes are His also, but "I believe in God the Father Almighty." Why is this? It is plain why—because this attribute is the reason why we believe. Faith is the beginning of religion, and therefore the almightiness of God is made the beginning and first of His attributes, and just the attribute which ought to be mentioned in the Creed. We should not be able to believe in Him, did we not know that He is almighty. Nothing is too hard to believe of Him to whom nothing is too hard to do. You may recollect that when it was prophesied to Abraham that the old Sarah his wife should have a son, Sarah laughed. Why did she laugh? Because she did not bear sufficiently in mind that God is almighty. Therefore the Lord said to her, "Is anything hard for God?" (Gen. 18). And in like manner our Lord in the Gospel of this day, when He commanded the winds and the sea, said "Why are ye fearful, O ye of little faith?" If they had had a firm perception of His almightiness, they would have been sure that He could bring them out of danger. But when they saw Him asleep in the boat, they could not believe that they were safe, not understanding that He, awake or asleep, was almighty.
This thought is very important to us at this day, because it will be a means of sustaining our faith. Why do you believe all the strange and marvellous acts recorded in Scripture? Because God is almighty and can do them. Why do you believe that a Virgin conceived and bore a Son? Because it is God's act, and He can do anything. As the Angel Gabriel said to the Blessed Virgin, "No word is impossible with God." On the other hand, when holy Zacharias was told by the Angel that the old Elizabeth, his wife, should conceive, he said, "Whence shall I know this?" and he was punished at once for disbelieving. Why do you believe that our Lord rose from the dead? Why, that He redeemed us all with His precious blood? Why, that He washes away our sins in Baptism? Why do you believe in the power and grace which attends the other sacraments? Why do you believe in the resurrection of our bodies? You believe it because nothing is too hard for God—because however wonderful a thing may be, He can do it.
