Let me explain. When I was young I kinda wanted to be a missionary. Travel the world, meet new people, experience exciting new adventures. Did I understand what it meant to be a missionary? Not at all, but it sounded fun. However, life moved on and come 12th grade I had to decide what to do with my life. I decided to get a business degree. I met this guy while we were still in school, he was super handsome and a lot of fun. He was in Bible College preparing for camping ministry. We eventually started dating and the summer we got engaged he went on a missions trip to Jamaica. The first phone call he made to me when he returned I knew he wanted to move to Jamaica. Of course, he didn't tell me because he didn't want to freak me out, but he didn't have to tell me, I knew (and yes, I did freak out). I had never even been out of the country and the farthest west I'd been was probably Huntsville, Al. Me, move away from all my family and friends? All that I'd ever known? Not likely pal.
The funny thing about his wanting to go to Jamaica was that he never had a lightning bolt experience or felt "called". What happened was he saw a need and was willing to help, and the Lord gave him compassion for the people he ministered to on that trip. Did he have compassion for Jamaicans before he went? No, but as he was there and was among them the Lord moved his heart with love.
After I freaked out A LOT, I ended up deciding that if that's what the Lord wanted then I would at least give it a shot. So in our premarital counseling our wise pastor advised us to visit Jamaica before we moved there. And he told my man to let me decide for myself how I felt about it. So after we had been married about 5 months to Jamaica we went. I still remember the first time riding to the house from the airport. We came to the small town of Hopewell and there were people absolutely everywhere, and there were bars on everything. All I remember was thinking "What in the world was I thinking?! This is absolutely crazy, there is no way I am moving here!" Of course, I didn't tell my husband because we had only been on the island for about 20 minutes at this point. But my mind was already made up.
Long story short, by the end of the week the Lord had completely changed my heart. I didn't even want to return to the States. Did I feel "called?" No, I didn't have that lightning bolt experience that modern Christian culture has made me believe I need to have, but I had a love for the Jamaican people that I could not and cannot shake. I can guarantee to you that it was not my sinful self that wanted to up and move to a developing country. The Lord worked on my heart, but not through a lightning bolt, little by little, day by day.
So does it mean that you have to audibly hear the Lord tell you where He wants you? I would say no. Isaiah 6:8 says "And I heard the voice of the Lord saying, "Whom shall I send, and who will go for us?" Then I said, "Here I am! Send me!" Isaiah overheard the need, and was willing to go. So that is how the Lord started working on us. We saw a need and He gave us love and compassion for the Jamaican people that we cannot get rid of.
I would encourage you, you may not feel "called" to volunteering at the soup kitchen or teaching children, or mentoring a younger person etc. But have you even given it a shot? The Lord just may give you compassion once you try it out. After all, Jesus had compassion on those who were around Him, it could be the same for you.
