Such is the effect of Jesus shedding His holy blood that it facilitates actual fellowship even with The Father. And fellowship with Jesus is fellowship (being on good terms and in partnership) with the man who lives always who is devoid of sin and always has been. It is quite something! Even those who confess to sin and live by truth but have yet to know in their spirit the spirit of Jesus which reaches out to His fellows, these can still be on good terms with those who have this fellowship with Lord Jesus and can still be in touch with the Holy Spirit who is all about truth and honesty. We can all have some share in this love if we all confess we have missed perfection at times and we love and hold to Jesus Christ's teachings and truth. His blood enables this.
