As all long distance runners will know, stamina is important in running the race- but mental endurance is equally important. If I run with the mindset that I am tired and I can't do this, the chances of me dropping out of the race becomes exceptionally high.
This is like our race in faith. Life can sometimes throw us a curved ball, and future may suddenly seem bleak. What you used to be confident about may suddenly cease to exist, and your life may be thrown into chaos. Yes, it is difficult. In fact, what you are experiencing now is perhaps so much that it may even crush another if they were to experience what you are undergoing.
The good news is, the very substance of the stamina we so seek to run this good race of faith has been given to us. Jesus- the author and finisher of our faith- is that substance. Therefore, from the very moment we say yes to Jesus, we have been given the ability to finish this race. All we need to do is to focus on Him.
Peter walked on waters when he kept his eyes on Jesus. What is your miracle today?
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, 2 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.
