I pray something similar to this at least once a week. It took me a long time to get to the point where I could ask to be put in this position. It started years ago when a neighbor, who sent her kids to a Christian school but I'm pretty sure had never stepped foot into a church, complained to me that the school scared her kids by talking about heaven and hell and being saved.
It was a perfect opening to share the Gospel with her. But I didn't. I didn't have the words and I was afraid of saying the wrong thing. I've regretted that missed opportunity ever since.
Even so, I didn't start asking for another opportunity right away. Like I said, I was afraid. I imagine I felt the way Moses did when God told him to go to the Pharaoh and ask to let the Israelites go. Who am I that anyone would listen to me? I can't speak eloquently and I didn't know what to say.
It would have been pretty cool if God had given me a staff that turned into snake, but He didn't. Well, to be fair, I didn't ask, but I'm not so sure He would have anyway. Instead, He's steadily provided me with knowledge and confidence through the years.
I started praying for those opportunities several years ago. I haven't witnessed any dramatic transformations, but I do think I have planted plenty of seeds. I also feel that I've changed some minds about what a Christian is really like. You know those people who think that Christians are all pious and judgmental? Yeah, I've met plenty of them and I believe that I've shown them that Christians are just regular people, like them.
I also think that I've shown Christians and the unsaved alike the love of Jesus. Everyone needs a little love now and then and I'm always happy to brighten someone's day.
So, I ask God to put me in someone's path, knowing that He'll give me the words and the courage to say what they need to hear.
