The Golden Chain of World Missions

Brethren of the Reformed faith are well acquainted with the "Golden Chain of Redemption" from Romans 8 which has 5 indissoluble links in the chain: 1. Foreknew, 2. Predestined, 3. Called, 4. Justified, 5. Glorified. But are we as familiar with the "Golden Chain of World Missions" found in Romans 10? In reverse order these five links are: 1. Call, 2. Believe, 3. Hear, 4. Preach, 5. Send. Each of these are non-negotiable and indissoluble. What part do you have in this golden chain?
