From church of Christ in Conway, Arkansas. The following three Bible study websites you may find useful.
The first Bible study is entitled: "Are You A Member Of The Lord's One True Church?" at http://www.netbiblestudy.net/church . In this Bible study we will see that the Bible says that the Lord has only one true church and this one true church does not include any of the many denominational churches.
The second website is entitled: "Denominational Doctrines" at www.netbiblestudy.net/denominations . This study contains brief descriptions giving where and when each of the denominations listed began and who started them. Also given are some of their basic beliefs especially what they falsely teach and practice that one must do to be saved and why what they teach is false.
The third website is entitled: "Are You Really Sure Of Your Eternal Salvation?" at http://www.netbiblestudy.net It is an interactive Bible study course consisting of 25 lessons. The purpose of this course is to teach the non-Christian what he must do to be saved.
Yours in Christ,
