To follow all these dreams I have and use them for your glory

Yesterday I heard a guy in a video say this:
“…We need to find that one or two things that God has wired us for and offer it back to him, be the best we can at it and He will then use it for His Glory…”
Drawing, painting, singing, playing instruments, each one of those is an obvious talent which can be seen or heard. But what about if you haven’t discovered those things yet? I can honestly say that I am one of those people that first came to God thinking… “but what if you don’t have any talent??” and I’m sure that a lot of young Christians can relate to that, maybe even some older ones. It wasn’t until I was two years into my walk with God that I realized that he had gifted me in preaching, encouraging and writing (don’t worry folks, what you see in this blog isn’t the polished form of my writing, it is very informal. Not many people have read my actual writing. Lol)
To be honest there are times in which I feel that I am simply choosing to hide my talent under a rock or in a hole or something. I know I can be doing so much more, but I’m not. A lot of the time it is due to my own insecurities and doubts. May God Help me to be more confident but more so, to trust and believe him!
Is there anybody out there that understands what I’m saying? Have you ever felt like you were hiding your talents and letting them waste away while God has clearly called you to use them for His Glory??
