In 1898 and 1899, A. T. Jones wrote, in the Advent Review and Sabbath Herald, a series of articles on Faith.
He used a statement by Ellen G. White as the basis for this series and they are well worth the reading and understanding.
"How to exercise faith," she said, "is the science of the gospel. . . . The knowledge of what the Scripture means when urging upon us the necessity of cultivating faith, is more essential than any other knowledge that can be acquired. We suffer much trouble and grief because of our unbelief, and our ignorance of how to exercise faith. We must break through the clouds of unbelief. We can not have a healthy Christian experience, we can not obey the gospel unto salvation, until the science of faith is better understood, and until more faith is exercised."
May God bless as we read and learn the science of the gospel - how to cultivate faith!
