Serving is how we follow the examples of Jesus. In John Chapter 13, Jesus went out of His way to wash His disciples' feet and explain to them that just as He served, so they should serve.
Read through the options carefully. Feel free to call the church staff to find out more about a ministry. Even if you have served in the same area before, become familiar with other areas of service so you can remain open to the Holy Spirit's leading.
Every Christian has a Spiritual Gift given by God to accomplish His plan for your life. See Romans 12, 1 Corinthians 12, and Ephesians 4 in your Bible.
In addition to your Spiritual Gift, your natural abilities can guide your choice of service as well.
Serving with others you know can be a great way to enjoy fellowship. But don't limit yourself: volunteering together can also be a great way to meet new people.
Even if you aren't sure what to do, sign up for something. God will bless your willingness and you'll gain more wisdom in the process.
