It is the blood of Jesus, the Son in the Trinity, that makes possible our entry into the heavenly holy of holies of this Trinitarian fellowship.  This fellowship is for those who have walked out of darkness and now walk in the Light.  There is a cleansing from sin in this walk/relationship.  This cleansing fits us for the holy place of fellowship with the Father, Son and Spirit because we have been “sprinkled clean of an evil conscience” (Hebrews 10:22).  Worship the Son, without Him you would not be here. 

“If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth; but if we walk in the Light as He Himself is in the Light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin” (1 John 1:6-7 NASB).
