The Christian life is a marathon, not a sprint. That means endurance is key. But how do we build endurance in the spiritual life? How do we stick with it to the end? This is such an important aspect to embrace so that we aren’t crushed when living the Faith gets hard or exhausting. Looking at our Gospel lesson we see Jesus praying the High Priestly Prayer of John 17 and in this prayer, we discover the key to running the marathon and not giving up! The three keys to endurance will make you able to finish the race well.
