In his book "Heaven on Earth," Thomas Brooks wrote, "A man may be a true believer, and yet would give all the world, were it in his power, to know that he is a believer. To have grace, and to be sure that we have grace is heaven on this side of heaven." James Fraser endured a long conflict with doubts. This little book, taken from his "Memoirs," is a helpful record of how he overcame his fears, and arrived at a firm assurance of his salvation in Christ.
