There hath no temptation taken you but such as is common to man: but God is faithful. (1 Corinthians 10:13)
Christian believers are wrongly taught if they believe that the Christian life is a guarantee against human trials and problems. If they believe that, they have mistaken earth for heaven and expect conditions here below which can never be realized until we reach the better world above.
There is a sense in which God makes no difference between the saint and the sinner. He makes His sun to rise on the evil and on the good, and He sends rain on the just and the unjust. It is strange that we rarely notice the other side of this truth: that God also visits His children with the usual problems common to all the sons of men.
If we cannot remove our problems, then we must pray for grace to endure them without murmuring. We will learn, too, that problems patiently endured will work for our spiritual perfecting. Think of our Lord and Savior—He was surrounded by enemies from the moment of His birth. They constituted a real and lasting problem which He simply had to endure for the period of His earthly life. He escaped it only by dying!
