Philosophy of Missions

Evangelism & Discipleship

“Do the work of an evangelist, make full proof of thy ministry.” 2 Timothy 4:5

As a dedicated team of missionaries, we proclaim the good news of salvation through faith in Jesus Christ. We are fully convinced of the sufficiency of God’s Word and the power of God's Spirit to save and transform men and women, boys and girls, into devoted followers of Jesus Christ.

Reproducing Churches

“So were the churches established in the faith and increased in number daily.” Acts 16:5

Evangelism and discipleship must yield local churches where believers can worship God, edify one another, and be equipped for the work of the ministry. Our objective is to establish reproducing local churches with Biblically-qualified leadership, expositional preaching, commitment to financial stewardship, vision for local and global church planting, and appropriate facilities for ministry.

Leadership Training

“Commit thou to faithful men, who shall be able to teach others also.” 2 Timothy 2:2

We are committed to strengthening local churches by equipping men and women for Biblical ministry.  Current efforts are focused on four-year Bible training programs in partnership with local pastors and missionary colleagues.

Camp Ministry

“Let no man despise thy youth, but be thou an example…” 1 Timothy 4:12

Camps provide an excellent environment for evangelism, discipleship, and supporting the establishment of local churches. Over 60 years of camping history, many have been saved, edified, and dedicated their lives to serve the Lord. We work alongside our national colleagues to develop the full potential of this valuable ministry.
