Charles Simeon (Pastor and friend of William Wilberforce) preached several messages on the shield of faith.
Here is his conclusion about the tremendous promise which belongs to those who have faith.
I found these words to be tremendously comforting.
“If you search the annals of the world you shall not find one single instance wherein believers were ultimately vanquished. On many occasions they have been wounded, and sorely at times; but believers are secure from any fatal stroke. Our Lord Himself has pledged His word that they shall never perish; that if they fall they shall be raised up again and that Satan himself shall finally be crushed under their feet.”
