It is finished—not I am finished
Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.
–Hebrews 12:1-2
Consider Jesus as the supreme example of a finisher.
Notice that our Lord did not say “I am finished”. Jesus had that pure undivided heart focused on the joy that was set before Him. He would not be hindered by the “sin that so easily entangles,” but rather was able to say in victory:
It is finished.
Jesus demonstrated a focused heart that would not be sabotaged by His own pain, struggle, weakness or distraction. His deep desire was only to please the Father and win the prize.
Paul called a young leader Timothy to have an undivided heart for God like a soldier whose aim is only to please his commanding officer. “No soldier gets entangled in civilian pursuits, since his aim is to please the one who enlisted him.” (2 Timothy 2:4) because Satan wants to capture Timothy to do his will! (cf. 2 Timothy 2:26)
Get rid of all the things that might entangle, especially your own sin.
That’s why the writer of Hebrews describes it as that “the sin that so easily entangles,” it is so easy to get caught up in the weeds of our own untended sin garden. A trait of a finisher is the undivided heart.
How many times have you said: I am finished. I am done. I just cannot do this anymore. I quit.
Having the undivided heart to please only Jesus will free you to see clear to a focused pursuit that never quits. How can you regain that pleases God alone? What sin in your life is so easily entangling your heart? Is it your own sin? Or is it the sin of others? The Lord would hear you say with Jesus: “It is finished.”
As we become entangled and get dragged deeper and deeper into a hole, I like to say, “Fight your way out of the hole”. No good can come from giving up.
