Evangelism: Avoid others' foundations?
What does "not building on another man's foundation" teach about evangelism strategies?

Setting the Context

“ And so I aspired to preach the gospel where Christ was not known, so that I would not be building on someone else’s foundation.” — Romans 15:20


What the Phrase Meant for Paul

• Paul saw unreached territories as his primary calling.

• He respected the work already started by others and avoided duplicating their labors.

• His aim: enlarge the Church’s reach rather than shuffle believers from one gathering to another.


Biblical Parallels and Reinforcements

2 Corinthians 10:15-16—Paul speaks of “areas beyond” rather than boasting in another’s labors.

1 Corinthians 3:6-10—Paul and Apollos serve uniquely: “I planted, Apollos watered… Each will receive his own reward according to his labor.”

Acts 13-14—Missionary journeys illustrate the pattern: entering synagogues or city centers where Messiah had not yet been proclaimed.

Matthew 28:19-20—The Great Commission mandates global reach, not mere reshuffling of the reached.


Principles for Evangelism Today

• Pursue the Unreached

– Identify communities with little or no gospel presence.

– Use culture-bridging methods: language learning, contextual illustrations, long-term presence.

• Honor Existing Work

– Support faithful ministries already serving an area rather than competing with them.

– Offer partnership when invited; otherwise, move to untouched fields.

• Build, Don’t Borrow

– Prioritize conversions over transfers.

– Allocate time and resources to fresh outreach initiatives instead of attracting members from neighboring churches.

• Embrace Complementary Callings

– Planters and waterers are both vital; celebrate variety of gifts.

– Equip new believers to become self-sustaining congregations able to disciple others.

• Keep the Gospel Central

– Salvation through Christ alone must remain the core message.

– Avoid distractions of secondary issues when introducing the faith to first-time hearers.


Practical Steps for Modern Ministry Teams

1. Conduct demographic research to locate unreached pockets—urban high-rises, refugee clusters, rural hamlets.

2. Form small, flexible teams trained in cross-cultural communication.

3. Engage through service: literacy classes, medical clinics, disaster relief—opening doors for gospel conversation.

4. Translate Scripture portions into heart languages; distribute digital and print copies.

5. Develop local leaders quickly; hand off authority as soon as biblically sound.

6. Maintain prayer and financial support networks at home, ensuring sustainability without imposing foreign control.


Expected Outcomes

• New communities of faith where none existed.

• Greater unity among existing churches, freed from unhealthy competition.

• A clearer testimony that the gospel is for every tribe, language, people, and nation (Revelation 7:9).

By following Paul’s example of “not building on another man’s foundation,” evangelism remains outward-focused, innovative, and faithful to the Great Commission’s global vision.
