They happen for a reason.

Things in life move with twists and turns and they happen for a reason. So if you doubt why something happens to you, remember: we can never learn to be brave and strong if the only thing in this world is happiness. 

Do not strive to be happy but strive to be good because being happy is not always good but being good will always lead to being happy. 

Because the bible says in

Psalm 68:3

But may the righteous be glad and rejoice before God; may they be happy and joyful.

Just have Faith because Faith expects from God what is beyond all expectation. 

— When nothing on which we can lean remains,When strongholds crumble to dust,When nothing is sure but that God still reigns,Then that’s the time we should trust!— 

And the bible says in 

Mark 5:36

 Overhearing what they said, Jesus told him, “DON’T BE AFRAID; JUST BELIEVE.”
