A megachurch pastor who was mentored by Ravi Zacharias warned 4,000 missionaries, ministers, and church leaders at the International Conference on Missions (ICOM) on Friday about the dangers of not holding leaders accountable. "Those who are on the wrong path are depending on you to give them the ultimate benefit of a doubt," said Jeff Vines, pastor of One&All Church in San Dimas, California, and the outgoing president of ICOM, during his keynote address. ICOM brings together about 300 missionary and missionary-serving organizations associated with the Independent Christian Churches and the Stone-Campbell movement.
