Hebrews 12:1-2 Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
Why do we always feel like giving up? I think it's just natural as a human being and God understood that so he gave us the scriptures that sometimes feels like a coach talking to the team. These verses are a spiritual pep talk to help us keep going as we do life. The world bombards us so much and we need to be constantly reminded that God is bigger than everything we encounter on a daily basis. Studying the scriptures helps to shoot adrenaline into our souls!
