When trials come to a christian, we are taught in the Bible how to cope from a christian prospective. First, the trial that comes from us from the lot of fallen humanity. There is no indication in the New Testament that by becoming Christians, we are insured against the kind of trials that affect the human race. Christ said to his followers, In this world ye shall have tribulation, but be of good cheer I have overcome the world. To think in the terms of "just name it and claim it" is false and misleading.
Second, there are trials that are in the plan of God. We are his children and he deals with us as such. Hebrews 12:9-11, teaches us about God's discipline. No one likes to be "corrected" or chastened, but God has a devine purpose for this. It yieldeth the peaceable fruit of righteousness unto them that are exercised thereby.
Third, Satan, our "adversary." 1 Peter 5:8, the devil has always been at war against peace and joy. How does a Christian cope? Count it all joy when ye fall into divers temptations. James 1:2. To welcome them as friends, takes the devine grace of God to help you.
