This leaves all the rest, ipso facto, as senders. You see, just as surely as God calls some to go, he calls others to stay. And what he desires most of all is your obedience. First, you may find that you have a burden for peoples of other cultures to come to the Lord. More than that, you have a desire to take the gospel message to them.
Goers often feel inadequate for the task.
They struggle with the thought of leaving family and friends behind. What keeps them going is a driving desire for God to receive the full glory due him from all the nations and for all peoples to have the opportunity to hear the gospel. It makes the sacrifices worth it. Goers have heard all the statistics of how many are lost without Christ and have brought that need to the Lord in prayer. This very act of considering the need and praying for a solution has led them to be the solution.
