The Church’s major task is to evangelise and make disciple.  OBC has been doing this since its early days.  But the formalised ministry of evangelism is a recent creation among several other ministries.

Objectives of Evangelism
1. Conduct evangelism through altar calls from the pulpit.
2. Conduct evangelistic outreaches through door to door sharing and open air preaching.
3. Firmly establish a member in the Lord through teaching and nurturing and guide him/her to a Church group where he/she can have meaningful fellowship, bible study
and spiritual growth.
4. Baptize by immersion all who receive Jesus Christ as their Lord and Saviour, attend OBC, and are not ignorant of the faith in Him.
5. Be missions oriented through evangelism, caring and Church planting.

Evangelism Vision
Every believer a disciple a year
