I want to give something back to my church and I have no idea where I would fit. Where do I even start?

“And I have filled him with the spirit of God, in wisdom, and in understanding, and in knowledge, and in all manner of workmanship, To devise cunning works, to work in gold, and in silver, and in brass, And in cutting of stones, to set them, and in carving of timber, to work in all manner of workmanship.”

When the tabernacle was being built, the first person scripture describes as filled with the Spirit of God is a craftsman, named and gifted for metalwork, stonecutting, and carpentry. Not a priest, an artisan. The Old Testament's picture of serving God's dwelling included practical skill from the very beginning. Whatever you happen to be genuinely good at is far more likely to be relevant than you assume.

“As every man hath received the gift, even so minister the same one to another, as good stewards of the manifold grace of God.”

Peter writes to scattered believers about ordinary church life and treats gifting as something already given rather than something to be located through years of agonizing. His framing is stewardship: you have received something and it is meant to be spent on other people. That removes the pressure to identify your one true calling before you are permitted to be useful this month.
