day no. 15,369: the answer is, "Yes"

Q: Should I stay or should I go now?

1 Samuel 30:17-25
And David struck them down from twilight until the evening of the next day, and not a man of them escaped, except four hundred young men, who mounted camels and fled. David recovered all that the Amalekites had taken, and David rescued his two wives. Nothing was missing, whether small or great, sons or daughters, spoil or anything that had been taken. David brought back all. David also captured all the flocks and herds, and the people drove the livestock before him, and said, "This is David's spoil." Then David came to the two hundred men who had been too exhausted to follow David, and who had been left at the brook Besor. And they went out to meet David and to meet the people who were with him. And when David came near to the people he greeted them. Then all the wicked and worthless fellows among the men who had gone with David said, "Because they did not go with us, we will not give them any of the spoil that we have recovered, except that each man may lead away his wife and children, and depart." But David said, "You shall not do so, my brothers, with what the LORD has given us. He has preserved us and given into our hand the band that came against us. Who would listen to you in this matter? For as his share is who goes down into the battle, so shall his share be who stays by the baggage. They shall share alike." And he made it a statute and a rule for Israel from that day forward to this day.

Q: Should I stay or should I go now?

A: Yes! One or the other.

Those who keep watch and hold down the fort enable those who go out to be fully out. They can leave without also having to worry about what's left behind. They are able to go knowing that reliable people have stayed.

Acts 1:8
But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.

In order for the great commission to be fulfilled, some will need to stay, some will need to travel and some will need to move altogether. Those who remain in order to witness to Jerusalem make it possible for those going to Samaria to know that the Gospel doesn't evaporate behind them. The point of planting churches is to see them bloom where they are planted, which means some must stay to water while others must sow somewhere else in order to cover the world in the sweet-smelling aroma of the Gospel.
