Fastening becomes a little more complicated in human relationships. But when basing our future on the decisions of others we seek as much assurance as possible that they will be stable. So in our financial dealings we use contracts. In marriage, we want vows of lifelong commitment to create the stable relationship necessary to build a family. Nations are held together by patriotism and in sports it is the power of competition and desire to win that holds a team together.
The Scriptures also use these terms to describe the essential need for those who make commitments to each other to keep their promises. Both the Old Covenant and New Covenant depict a binding agreement between God and those who want to have a relationship with Him. God has revealed His own character to us as unchanging and completely reliable. He is faithful, never lies, never changes, and always keeps His promises. Any commitment we make with Him is guaranteed, at least on His side:
- “Thus God, determining to show more abundantly to the heirs of promise the immutability of His counsel, confirmed it by an oath, that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who have fled for refuge to lay hold of the hope set before us.” (Heb. 6:17-18).
