The LORD says:

You need endurance in order to persevere.
If you do not have heart to endure, you will
struggle to persevere.  As I build My
character in you and teach you My truth,
I will begin to strengthen you so you can
endure the road ahead.  As you endure,
you will have encouragement to persevere.
You need to keep going.  I will not only
help you each step of the way, I will reveal
Myself to you in new ways as you prevail
through your trials.  I am your strength.

Hebrews 10:36-
"For you have need of endurance, so that
after you have done the will of God, you
may receive the promise."
