One of the easiest things for any of us to do when it seems like nothing is going our way, is for us to just give up and QUIT on God. That's right, just "throw in the towel" and walk away. What is really ugly is that the enemy will always be there, ever ready to pat us on the back and console us with, "you have good excuse to quit, you did your best”.
The one thing giving up will NOT give you is peace. The decision to quit on God will haunt you till the day you repent. You will be plagued with what might have been had you only persevered and waited on the Lord.
We have a race to run and we are running for an incorruptible prize. If we are going to make it, we must ENDURE to the END. It takes great effort to be a winner. As Paul said “and let us not be weary in well doing: for in due season we shall reap, IF we faint not.” Paul wanted those he was addressing in his letter to the Galatians to know he realized the struggles they would have to face, and that they might even get tired of living right. He, however, wanted to admonish them to "keep on keeping on" for God: he wanted them to "stick with it" and keep on sowing the precious word that they might reap and bring lost souls to Christ.
