Genesis 17:13-14
Come and understand the term Circumcision and Uncumcision as it applies in different ways. In the Old Testament in physical terms, it represented an everlasting covenant. In the New Testament in Spiritual terms, it applies to circumcision of the heart. The uncircumcised in heart are rebellious, proud, stiff-necked and hard-hearted. Circumcision of the heart causes us to love Him wholly and delivers us from self-love.
