It is understandable if you decide to quit, this is your right, having a free will. In quitting, you will miss a better blessing and the true purposes for all the difficulties you have experienced.
You have already endured the impossible and survived the scandalous, why not finish the race. Get the prize for your efforts and the hardships, that were conquered.
There is no credit for beginning the race, only those that finish are acknowledged, as such. Pack away your pride. Quitting is permanent, but the discomfort is temporary.
Put your feelings in perspective, this hurt will eventually heal. This pain is short lived, but to destroy all that your sacrifices have built, would like burning down a house, because the roof leaks.
1 Corinthians 9:24-27
Do you not know that in a race all the runners run, but only one receives the prize? So run that you may obtain it. Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable. So I do not run aimlessly; I do not box as one beating the air. But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.
