All Believers in Christ's church are here because of Missions. Just look at the Book of Acts. From one believer to another until you and I heard the Word resulting in the Grace of Salvation. No doubt you and I have spoken the Word that has resulted in the same gift of Grace, a soul being Born Again. It's just what the church does.
Here is a list of Missions supported by the Comstock Church of Christ. Most of these names include hyperlinks to their own web sites so you can discover their ministries.
