Each ESI group meets once a week for 2 ½ hours. ESI is made up of 6 modules, each module lasting 20 weeks. Each session consists of a 2 hour interactive discussion on a Biblical or Theological topic, and the last half hour is spent in accountability groups of 3 ESI participants. During the accountability time each participant shares honestly and deeply about temptations he is facing, how he is finding victory, and the nature of his passion for Christ, how he is engaging in evangelism — and then they pray for each other.
