You have gifts that God gave you. They might not seem like to much and that's ok. God will multiply them but you have to be willing to let them be used for Him. I don't know what all your gifts are but I know that God gave them to you for a reason. They can be used to bring people closer to God and put more good in the world. I don't think you need to proclaim your faith to everyone through your gift. By that I mean I think the most powerful way to lead people to God a lot of the time is to be there for them, love them, and then maybe tell them about God or just be His light in the world for them. Now if your gifts is teaching others that's awesome I'm just saying not all gifts directly teach others about God. I encourage to think about what you're good at, you don't have to tell anyone but just come up with something that you think is a gift God has given you. Often it's something that you love, like for me I think one of my gifts is writing and I use it for God through my devotional books. No one has the same gifts and that's good so we can all work together and make amazing things happen.
