The first systematic expression of dispensationalism was formulated by J. N. Darby sometime during the late 1820s and 1830s in the British Isles. I believe that Darby’s development was the culmination of various influences which produced within his thought one of the most literal approaches to Bible interpretation in history and a theology which distinguishes God’s plan for Israel from God’s plan for the church. The most well known feature of dispensational theology is the much-debated pretribulational rapture doctrine.
