BUT .... that's not you. You are quite sure that you are not one of those called servants. So, now what should you be doing?
You could start by asking God that question. He will surely lead you to larger involvement in the Great Commission through being an avid Sender, or Mobilizer, or Partner in some form. Your CROSS experience will not be wasted! If it takes 9 support people behind every 1 on the front lines (in military terms), it surely takes that many to support, pray for, and enable a missionary to make it and thrive on the field.
What can you do, in practical terms,
- to help someone get to the field?
- to get your church focused on reaching the unreached?
- to give your time to provide margin for preparation to a friend who is called to be that go-er?
- to pass on the biblical passion and drive to recruit others in the task?
Never let yourself think that your CROSS experience will not be used by God in some great way for Him. If you look for opportunities to build on what you've learned and how your heart has been stirred, surely God will provide outlets of service for you that produce fruit for His kingdom expansion. Keep growing in prayer, giving, serving, teaching, encouraging, loving for missions. God will be honored by your obedience, even staying "at home". You will be enriched beyond your imagination!
