There is no victory without a battle, there is no growth without an obstacle to overcome, there is no faith without a miracle to believe God for, there is no testimony without a trial. If you are going through a hard day, month, or even year remember this: it won't last forever. God will get you through. And when it all ends you will look back and realize that the lessons, the strength, the faith that you gained in the process of your struggles was all worth it.
Trust God for the hope that tomorrow holds even if today you find yourself in the dark. He will always be faithful to you.
