1 Corinthians 10:13 No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it.
Now we could all try to disagree with this because of the many temptations we face and fail at; but there is method to this all.
Christ wants to strengthen us to live in this world and to help out others who are less able to live by faith.
He allows things to happen in our lives, not to tempt us, but to strengthen us for what may be ahead. If we did not exercise we may not be fit enough to endure the road ahead!
