Is anyone of you in trouble? He should pray. Is anyone happy? Let him sing songs of praise.
1 Peter 5:7
Cast all your anxiety on Him, because He cares for you.
Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Who of you by worrying can add a single hour to his life?
Hope after reading this you will feel more relaxed before any major exam or anything you are anxious about, always know that God loves you and will take care of you! =D
