In Romans 5:3-5 we read:
…not only so, but we also glory in our sufferings, because we know that suffering produces perseverance, perseverance character and character HOPE. And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us.
It can be hard to hope, when you’re at your lowest, but it’s when you’re at your lowest that hope may be the only thing you have left to hold onto. So hold onto hope, and hold onto God, no matter what.
