The Christian life is characterized in Hebrews as a Race we run. It is a race we as Christians have chosen to run, and if we have chosen to run it, Paul says We need to “Run with perseverance, the race marked out for us”
In a nutshell: your eyes need to be fixed on the only one that can give you the strength to make it through that race, Jesus Christ. No matter what the distraction of the day is in your life, whether it be trials or temptations, pain or sin, family troubles or loneliness. Keep your eyes fixed on Jesus. After reading this from Hebrews, you might ask, how do I apply that to my life today.
