‘Tis not God’s design that men should obtain assurance in any other way, than by mortifying corruption, and increasing in grace, and obtaining the lively exercises of it. And although self-examination be a duty of great use and importance, and by no means to be neglected; yet it is not the principal means, by which the saints do get satisfaction of their good estate. Assurance is not to be obtained so much by self-examination, as by action.”

Jonathan Edwards, The Religious Affections, Yale University Press, 1959, p. 195
