There are a lot of different ways to answer this question, but one perspective is that as Christians, we view endurance as a virtue. It's a quality that God values and calls us to develop in our own lives. Hebrews 12:1-3 says, "Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God." So in essence, we need to endure because it's part of God's plan for us. It helps us mature and grow in our faith, and it gives us hope.
