Signs and symbols are important because they are used to convey messages quickly and concisely. God gave a sign for every covenant that he made with men, as if to assure them of the certainity of His promises! God gave Noah the sign of the Rainbow (Genesis 9:13); gave Abraham the sign of Circumcision (Genesis 17:11) ; gave the Israelites the sign of Sabbath ( Exodus 31:13-17); gave the Church the sign of Baptism. (Refer: The seven covenants.) Interestingly, all these covenants were made with the righteous because God doesn’t make a covenant with the wicked but with those who by faith had received a righteouness. ‘By his faith Noah condemned the world and became heir of the righteouness that comes by faith.’ – (Hebrews 11:7) So righteouness by faith is not a new testament theology but something we find throughout the Bible. ‘What then shall we say that Abraham, our forefather discovered in this matter?’… What does Scripture day? “Abraham believed God and it was credited to him as righteouness.“‘ – (Romans 4:1-3) And as a sign of the righteouness he had by faith, he was given a sign of circumcision. “You are to undergo circumcision and it will be the sign of the covenant between you and me … My covenant in your flesh is to be an everlasting covenant.” – (Genesis 17:11-13) Many think righteouness is credited to them when they take the water baptism. Infact they received the righteouness by faith even before they were baptized, as Abraham did! ‘And he received the sign of circumcision, a seal of the righteousness that he had by faith while he was still uncircumcised.’ – (Romans 4:11) We have received this righteouness of Christ by faith even before we were baptized in water when we received the Spirit of God who imputes Christ’s righteousness to us. Signs of the covenant are therefore :-
1. A reminder of God’s covenant – God deliberately chooses to remember his covenant with us and so must we! “I have set my rainbow in the clouds and it will be the sign of the covenant between me and the earth … Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all the living creature of every kind on earth.” – (Genesis 9:12-16)
2. An assurance of God’s promises – God first gave his promises to Abraham when he was 75 (Genesis 12:1-3), cut a covenant when he was 85 (15:18) and gave the sign of circumcision when he was 99. ‘When Abraham was ninety nine years old, the Lord appeared to him and said,”… I will confirm my covenant between me and you and will greatly increase your numbers … Every male among you shall be circumcised.” – (Genesis 17:2-10)
3. A declaration of our faith – The sign of baptism is a public declaration of faith; of our good conscience towards God. ‘…Water symbolises baptism that now saves you also – not the removal of dirt from the body but the pledge of a good conscience towards God.’ – (1 Peter 3:21) We declare that ‘we are buried with him through baptism into his death in order that, just as Christ was raised from the dead … we too may live a new life.’ – (Romans 6:4)
There are two sacraments that Christ instituted. The sacrament of baptism is the sign of the covenant and the sacrament of Communion/ Eucharist is the celebration of the promise that was fulfilled, just as they observed under the old covenant, the Circumcision which was the sign of the Abrahamic covenant and the Passover which was the celebration of the promise made to Abraham to deliver his descendants from slavery. (Genesis 15:13-14) Amen.
