If the faith whereby I have laid hold on Christ to be my Savior be altogether wrought in me by the Holy Ghost through grace, then I defy the devil to take away that which he never gave me or to crush that which Jehovah Himself created in me. I defy my free will to fling what it never brought to me. What God has given, created, introduced, and established in the heart, He will maintain there.
Charles Spurgeon
