Romans 8:18, 28 

I consider that the sufferings of this present time are not worth comparing with the glory about to be revealed to us.

We know that all things work together for good for those who love God, who are called according to his purpose.

Philippians 4:6-7 

Do not worry about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.  And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
