This was the explanation given me: Covenant of Grace - this may be defined as that gracious agreement between God and the offending sinner, in which God promises salvation through faith in Christ, and the sinner accepts this by faith, promising a life of faith and obedience (John 1:12-13; 3:16; Rom. 10:9-10). If this is true, my question is, are baptism and the Lord’s Supper the signs (or seal) of the Covenant of Grace? I believe that covenants (e.g., Adamic, Abrahamic, Noahic, Sainaitic, etc., ) had their own signs (seals). Please, I need your help my beloved brethren. Your replies will be truly appreciated; I’m completing my studies and preparations on how to effectively present to my relatives that salvation is by grace thru faith alone. Thank you very much. God bless.
