I choose Grace, and Grace all day long. The Grace of God has been from everlasting, and shall be to everlasting. The covenant made with Abraham was based upon Faith through the Grace of God. The Blood of Christ was not needed that Abraham might live according to the Grace bestowed upon him by the Lord. The Blood of Christ was a one time event, a sacrifice once for all time. And like the scripture says in the book of Hebrews, that if you sin willingly after receiving the gift of God, then there remains no more sacrifices for sin, which would then make his blood of none effect. But if there remains to me no more sacrifice for sin, then the Faith that lies within my heart shall rest in the Grace that the Lord has bestowed upon me.
