As a Jewish convert and believer in the salvation of Yeshua, who has been redeemed and cleansed from all sin by the blood of Jesus Christ, could any of you give ONE NT promise that God has given and can only apply to the church and His body, that you truly believe in and are trusting God for as a NT believer. If you can, would you please mention what that promise is and give the reference in scripture from whence it comes.
