There is no doubt about assurance in the Word of God. A person said to me some time ago: "I think it is great presumption for a person to say she is saved." I asked her if she was saved. "I belong to a church," she sobbed. "But are you saved?" "I believe it would be presumption in me to say that I was saved." "Well I think it is a greater presumption for anyone to say: 'I don't know if I believe in the Lord Jesus Christ because it is written, He that believeth on me hath everlasting life.'" It is clearly stated that we have assurance.
