So God, willing more abundantly to show unto the heirs of promise the immutability of his counsel, confirmed it by an oath: That by two immutable things, in that it was impossible for God to lie, we might have strong encouragement, who have fled for refuge to lay hold upon the hope set before us: Which hope we have as an anchor of the soul, both sure and steadfast, and which enters into that within the veil; Where the forerunner is for us entered, even Jesus, made a high priest forever after the order of Melchizedek. (Hebrews 6:17-20)
