Some are trusting in their performance to perform well in not looking at self but at Christ, but they are still looking at their performance to not look at self and not resting in the performance of Christ. It is amazing the wickedness that prideful man will do to try to find rest on their own abilities. You will hurt and beat your head to death but you must give up!
Regardless of how we feel, if we have faith in what God says and trust it, we will not fall, we will not fail. The just shall live by faith not by feelings.
Do you trust the Lord even when you have no feelings? We need to remember that God often withdraws His sensible presence from us to test and purify our faith.
