Ever since the Garden of Eden, men have been in sin. Therefore, the New Covenant is designed to prepare the seed for the possession of the promises. It is the Covenant that relates to the forgiveness of sin. When the Lord Jesus Christ came, He inaugurated the New Covenant. At the Last Supper, Jesus took the bread and wine and said, “This is my body which is given for you, and this cup is the New Covenant in my blood, which is shed for you”. In other words, the Lord’s Supper is a symbol of His death.
It is sad to hear people say the Bible is no longer relevant for today’s living. The argument they present is that we live in a secular and scientific age where what was appropriate for John and Paul and the other people in the Bible is no longer applicable. This can be seen in the sociological schemes and church growth conferences that advise churches on how to be relevant. It appears that it is no longer enough just to study the Bible for what is being said; we apparently need a special technique to help us grow, in addition to the Word of God. We have churches today spending thousands on advertising and building their “empire” image, instead of investing in the harvest field.
