It could have mde him negative, down on God, bitter with the church. No, in all these things we are more than conquerors through him who loved us. The Corinthians were attracted to glory and power, power as domination, as power over, but Paul experienced the power of God in weakness and vulnerability, as power with those who struggle. Faith tempers pain by temporizing it. This, too shall pass.
Faith is an informed optimism.
It leads us to a positive, resurrection-affirming point of view. It leads us to choose the creative opportunities for growth each adversity brings. And it leads us to trust ourselves more into God's hands. The senses see only the action of the creatures, but faith sees in everything the action of God. Faith leads us to see the possibilities that lie hidden within our problems.
