There are some Bible verses that if you commit to memory could be an encouragement to a fellow believer who is going through some tough times. I for one like 1 Cor. 10:13.
"There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that which ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it."
Of course this verse has many aspects about trials. I really like the phrase 'but God is faithful...' He allows things to happen, but He is faithful in the midst of sending us trials (or temptations, another synonymous term). What is He faithful in?, well in this verse, we are guaranteed that our problems are sort of 'custom made.' We are not going to be tempted above that we are able to bear. Then another thing that He is faithful in, is that He provides a 'way of escape.' He does not provide a way to avoid the trial necessarily, but He provides a way so that we can bear it. The verse says 'that ye may be able to bear it.' Praise the Lord, He is loving and caring enough to make sure that our trials are a necessary means of making us better Christians.
