"...the way to achieve the greatest social and cultural transformation is not to focus on social and cultural transformation, but on the “conversion” of individuals from false religions to faith in Jesus Christ for the forgiveness of sins and the hope of eternal life. Or to put it another way, missionaries (and pastors and churches) will lose their culturally transforming power if they make cultural transformation their energizing focus."
Woodberry’s research supported this sweeping claim: Areas where Protestant missionaries had a significant presence in the past are on average more economically developed today, with comparatively better health, lower infant mortality, lower corruption, greater literacy, higher educational attainment (especially for women), and more robust membership in nongovernmental associations.
There is a biblical reason for this. The only acts of love and justice that count with God are the fruit of conversion. If repentance toward God and faith in Jesus does not precede our good works, then the works themselves are part of man’s rebellion, not part of his worship.
Thus John the Baptist says, “Bear fruit in keeping with repentance” (Matthew 3:8). That’s the transformation that counts with God: First repentance, then the fruit of repentance. And Jesus says, “Make the tree good and its fruit good” (Matthew 12:33). First a new tree, then good fruit.
Transformation comes through individual new creation...
“Conversionary Protestants” changed the world, because they didn’t focus first on changing the world, but on faith in Christ.
This means that the missionaries that will do the most good for eternity and for time — for eternal salvation and temporal transformation — are the missionaries who focus on converting the nations to faith in Christ. And then on that basis, and from that root, teach them to bear the fruit of all that Jesus commanded us (Matthew 28:20).
