Perseverence is patient endurance of hardship. Persisting in spite of difficulties and discouragement.
Perseverence pushes through when times are tough. I have experienced the tough times and stayed positive and prayed alot to Almighty God. He will never leave you in the valley, you will arrive on the other side. God never leaves us, it is we who leave him out of the difficult trials we experience.
From my experience, you can have peace in the midst of life's saddest trials. We persevere like a runner in a 26 mile marathon. Running the race with perseverance, the race which God has marked out for us. Hebrews 12:2 "Let us FIX our eyes on Jesus, the author and perfecter of our FAITH, who for the joy set before him endured the cross."
So do not grow weary and lose heart, your Savior did not give up when he was being persecuted. His motivation was his love for you and me.
