In Rom 4:7-8, Paul talks about how blessed the Jews were but this blessing is now for the Jews only it is universal.  The Gentiles receive the same opportunity.  Abraham’s faith was the thing that brought about his righteousness.  He believed and trusted in the Lord.  When did Abraham become righteous.  It was before the act of circumcision not after.  Being circumcised is the outward sign of an inward act.  God cuts our heart and changes us from the inside out.  No outward form or religious service will make us righteous.  Only the blood of Jesus Christ can do that.  Accept God’s provision, walk in unity with Him.  Live a life in the Spirit and trust God.  Every day is a journey of faith but at the end of the journey is well worth the trip.
