The Bible tells us how the mission will go forward—through prayerful dependence, gospel proclamation, biblical discipling, and church planting (Ex. 6:5–8; Rom. 10:17; Col. 4:2–4; 1 Thess. 5:11).
The Bible tells us what kind of missionaries we should support—biblically faithful, methodologically patient, gospel-proclaiming, church-loving missionaries (Acts 16:1–3; Rom. 10:14–15; 2 Cor. 8:23; 2 Tim. 4:1–5; 3 John 1–8).
The Bible tells us what the end goal of missions should be: transformed individuals in biblical churches who will ultimately join a heavenly multitude, praising the Lamb of God forever (Rom. 8:1–11; Heb. 10:19–25; Rev. 7:9–10).
That’s just a tiny sampling of what Scripture has to tell us about missions. We’re not left alone to lean on our own puny resources to figure out the mission of the church for the nations. God is much too kind and serious to have done that.
