Ekimr, I don't know you and exactly where you are coming from, so I thought I would give you what came to mind as I was reading this thread. I agree with all the replies, they are great, IMHO. I would like to add the stumbling block that I have, though, just in case you might be able to relate.
I have a strong desire to share the gift I have been given ( I mean Jesus, not evangelism). Everywhere I go I see the possibilities, and I have beautiful visions running around my head of such hopeful beauty. I ask myself, should I be evangelizing? I really want to. I really really want to. If I had the skills, I would love to. So it comes down to skills, right? I think for me, it comes down to courage and a willingness to bear the cross with Jesus. Not necessarily skills. Not that skills aren't important, of course they are, but for me the biggest part is not necessarily skills, but allowing the gift to be alive in me. The hard part for me, is being up front and honest about who I am. I think the skills will follow after I get through that mountain.
Personally, I believe ( at this point in time) that we are all in the process of growing in Christ. Receiving spiritual gifts isn't necessarily an all-at-once thing. Just as understanding the Word doesn't come all at once. I wouldn't doubt that many of the big leaders we know about, who are great evangelists, have been taught from an early age. They have gone through their learning, too. I really like Beth Moore. Her ministry has grown. She talked in a video, about some of the mistakes she made early on in her ministry. She was young once, too. She began somewhere, too. It didn't happen over night
as a dramatic gifting. She was inspiried. She DECIDED. She learned. She grew. And look at the wonderful things she is doing now.
So, I guess, what I'm adding is to remember that there is a beginning, and there is growth, even with the Holy Spirit's gifts. We are human. And like everyone has said, your relationship to God is central. But sometimes, the beginning is about courage, being willing to take the chance to act on the inspiration God has put in you, out of pure faith. And trust that the rest will follow.
Samuel has been mentioned. Yes, he had a close relationship with God. This is key. But Samuel's trust in the LORD was incredible. And his trust lead him to take risks in battles. He knew he could rely on God. Most likely, you're life will not be at risk if you step out and make a mistake. The worst that will probably happen is that you will be given funny looks and be thought of as strange. So there's room for mistakes, and fumbled beginnings. God has inspired you. I believe He has inspiried me too. But I'm at the very beginning - trusting God enough to find the courage to step out and begin. Getting close to God is reading the Word. So trusting Him is knowing and trusting the Word. And of course prayer. I almost forgot to support that. Then it's just a matter of going for it. And by all means, if you are interested in taking an evangelism class, I say go for it. These sorts of things can lead you to increased inspiration, they can give you ideas of your own, they can teach you important lessons. Sometimes they lead us to turn unexpected corners. Follow your interests. How else is God gonna lead you? He made you the way you are. You like the things you do, and are interested in the things you are because God made you that way. Make the most of it. Enjoy yourself. Really, enjoy your self. Let who you are take you closer to God. Just focus on Him and his will, and follow your inspiration. Maybe you do have the gift of evangelism, maybe you don't. Learning about it isn't going to harm you. At the very least, it can be interesting. Just focus on God and understanding His will. And have fun with it.
Like Samuel says, "Come on, let's go..." take the risk and trust in God. (1Samuel 14, New Living Translation)
...and find out.
May your blessings be rich.
