Keep the faith …..
Simon, Simon, Satan has asked to sift all of you as wheat.
But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers. (Luke 22:31-32 NIV)
In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. (Eph 6:16 NIV)
