Romans 8:28 (NIV)

"And we know that in all things God works for the good of those who love him, who have been called according to his purpose."

Trust in God. Even if things may seem horrible at the moment, or if you are unsure with what is going on, in your life, know that it is for your good. God will use hard times to build your character, and mold you into that man or women of God He has called you to be. Use this verse in prayer and meditate on it. Have it in your head 24/7 to counter the devil when he tries to corrupt your mind and make you lose hope. Remember this verse when things go well, also, to remind you of where God has brought you. Don't forget the purpose God has for you in this life, there is no task or challenge that God gives you that you cannot overcome. Live life knowing that in the end, you will and have, already won. God loves you!
