What should we do if two assemblies can't cooperate well on a joint project?

What Bible principles guide us regarding involvement in an outreach work that a neighboring assembly opposes?

While we are responsible to "go into all the world" with the gospel (Mar 16:15) and can see the need of souls in a neighboring community, some other Biblical principles may also apply to such a choice.

Each assembly is responsible to God for it own decisions. The Lord teaches this direct accountability when He introduces His instruction regarding an assembly (Matthew 18:18). Therefore, if an assembly is concerned about the people, methods, or associations of an outreach work involving its own believers, an assembly believer from a different assembly should respect that assembly’s concerns.

The safest course of action is to consult with those who guide (Hebrews 13:17 RV mg.) the assembly where you are. They likely have a better understanding of the issues involved. Perhaps they will know how it is possible to be involved in that outreach in a way acceptable to both them and the neighboring assembly. That is possible, but unlikely. The Lord’s awareness of His mission moved Him "into the next towns" (Mark 1:38) and we have "next towns" to visit with the gospel if the door is closed in one town.
