you can be sure
"These things have I written unto you that believe on the Name of the Son of God; that ye may KNOW that ye HAVE eternal life" (I John 5:13).
You may be satisfied (falsely so) because you have joined a church organization-this can be dangerous for your soul's eternal state it is false assurance.
The True Church is not an organization but an organism-like a body (I Cor. 12:12). You do not join it, you get BORN into it. Jesus said, "Except a man be born again, he cannot see the Kingdom of God." (St. John 3:3).
Your soul's salvation does not depend on "church membership" in any earthly church organization, but upon a personal faith in the Lord Jesus Christ as your own Savior. "Christ died for the ungodly." (Romans 5:6).
"He that hath the Son hath life; and he that hath not the Son of God hath not life." (1 John 5:12)
You can find reality (we would be glad to help you). Be saved today-be safe-and KNOW IT!
I want to accept God's wonderful offer of Salvation. I believe God loves me and that He sent His Son, JESUS CHRIST, to be judged for my Sins. With all my heart I believe that "Christ died for my Sins' and rose again and lives in heaven today. As best I know how, I here and now trust Him as my personal Saviour and commit my all to Him.
