Worship Elements: Sacraments Uncircumcision (Leviticus 26:41)

So often people think of the sacrament of circumcision as a physical sign while baptism is a sign of Spiritual renewal.  So, these signs might point to Christ, but they have radically different intentions.  When we survey scripture we find that this is not necessarily a true distinction with circumcision being physical while baptism is spiritual.  In fact, Moses teaches that one being uncircumcised is stating that one is not walking in power of the Lord.  So, can we really say that circumcision is not a spiritual sign?
