A former biology teacher who adopted and taught the foundational beliefs of evolution, he is now a zealous promoter/defender of biblical creation.

Over the past twenty years he has lectured at churches, conferences, universities, and educational facilities in over 40 countries with much of his time spent in the former Soviet Union.

His easy-to-understand teaching style communicates to people of all ages and backgrounds. Oakland's classes are always centered on the validity of Scripture with an emphasis on the importance of Christians being active in their faith by communicating this same message to others.

In 1965, Pastor Chuck Smith began his ministry at Calvary Chapel Costa Mesa. Only twenty-five people attended. What began as a small chapel has now grown into a church that seats over 2000 and is filled almost nightly. From the beginning, Pastor Chuck welcomed all, young and old, without judgment, placing his emphasis on the teaching of the Word of God. His simple, yet sound, biblical approach draws 25,000 people weekly.

With a sincere concern for the lost, Pastor Chuck made room in his heart and his home for a generation of hippies and surfers; generating a movement of the Holy Spirit that spread from the West Coast to the East Coast, bringing thousands of young people to Jesus Christ. Included among this generation of new believers were Greg Laurie, Mike MacIntosh, Raul Ries, and Skip Heitzig, as well as hundreds of others who now have ministries of their own.
