The blood of the everlasting covenant
One major problem of the Church today is that we are too glued to the past. An average Church person does not want the Scripture explained in new lights. We don't like to brush up, so we remain in the dark ages. We are not apt to welcome new things. There is only one Bible, very old, and every generation is supposed to solve their problems with it. The earlier we open the better.
"Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, make you perfect in every good work to do His will, working in you that which is well pleasing in His sight, through Jesus Christ; to whom be glory for ever and ever. Amen" (Heb. 13:20-21).
One of the things that gives the Christian faith its uniqueness is the Blood of Christ. That's what we believe. It's one of the things that are most surely believed among us (Lk. 1:1b).
The Scripture above speaks of a covenant between God and His Son Jesus that if He dies and sheds His blood, He God, would raise Him up again. The point is this: if the blood brought Jesus back from the dead, then it follows that the blood can bring us back from any condition and situations we may find ourselves in now. Not only that, it says we can be perfect and please God here on earth. Think about that.
