What we can say for sure is that, at the very least, God calls every Christian to live with a missionary heart.

If you are sure that He is calling and you can be sure that He will also remove the barriers that would preclude your service, in His perfect timing. Rest in that.

Hearing the missionary call has a great deal to do with what you are listening for.

When God calls His child to live the life of a missionary, He gives him the desire with the calling.

God will not lead you where He will not provide for you.

If someone does not have a missions heart at home, nothing magical happens when they buckle the seat belt on the airplane.

God has called every Christian to international missions, but He does not want everyone to go. God calls some to be senders.
