Blood brings you closer

"But now in Christ Jesus you who once were far off have been brought near by the blood of Christ." 

Ephesians 2.13

Blood is the only element that brings the human being closer to God. He who does not have the willingness to sacrifice his life by faith in the Lord Jesus Christ does not have what it takes to conquer it towards an eternity with Him.

Light and blood

"But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin." 1 John 1:7

To walk in the light is to walk according to the Christian discipline. And so we have unity among ourselves and the blood of the Lord Jesus purifies everyone of their sins.
