Here is An Open Letter to Seekers that Justin Taylor posted on his blog.It has been reprinted with permission from Moody Publishers, this is the Appendix (“A Letter to ‘Seekers’”) of David Clotfelter’s book, Sinners in the Hands of a Good God: Reconciling Divine Judgment and Mercy (Moody, 2004), pp. 266-274.

This letter concerning what is salvation and how does one know if they are actually a christian is so good that I plead with you to read it and to memorize it's main structure.
