C.H. Spurgeon on Assurnace of Salvation

C.H. Spurgeon wrote on assurance,

If one dear saint of God had perished, so might all; if one of the covenant ones be lost, so may all be; and then there is no gospel promise true, but the Bible is a lie, and there is nothing in it worth my acceptance. I will be an infidel at once when I can believe that a saint of God can ever fall finally. If God hath loved me once, then He will love me forever.
