All Christians have been commanded by Jesus Christ to share the Gospel message with unbelievers so that they too may be saved. However, few Christians regularly share the Gospel with non-Christians, and there are eternal consequences to this disobedience for everyone. A Markov chain model is proposed for estimating over time the proportions of persons who are saved and receive eternal life in heaven and who are condemned to hell. An evaluation and an analysis of the model are presented. Simulation results for the model indicate that a moderate increase in present personal evangelism efforts will result in only modestly more salvations over time. Therefore, substantially more intense evangelism efforts must be undertaken and sustained to make a significant difference in the number of souls that are ultimately saved. Sadly, some persons will choose never to be saved, regardless of how many and how often Christians share the Gospel.
