“各人要照所得的恩赐彼此服事，作神百般恩赐的好管家。 若有讲道的，要按着神的圣言讲；若有服事人的，要按着神所赐的力量服事，叫神在凡事上因耶稣基督得荣耀。原来荣耀、权能都是他的，直到永永远远。阿们！（彼得前書 4:10-11； 比较以弗所书4：11-16）
According to the Bible, every Christian receives at least one spiritual gift to serve the church.
"Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms. If anyone speaks, they should do so as one who speaks the very words of God. If anyone serves, they should do so with the strength God provides, so that in all things God may be praised through Jesus Christ. To him be the glory and the power for ever and ever. Amen. (1 Peter 4:10-11; Compare Ephesians 4:11-16)
So an important step in deciding how to serve in the church is to discover what our spiritual gifts are. Of course, we don't necessarily need to know what our gifts are to get involved in church service. In fact, we often discover our gifts in the process of serving.
Spiritual gifts are found in Romans 12:6-8 and 1 Corinthians 12:4-11, 28.
