The Bible is a book about covenants; so much so that when they decided to divide it into two sections they named the sections after the covenants found in them - the New Covenant and the Old Covenant. The word "testament" means a covenant.
A covenant is a formal agreement between two parties. It establishes an understanding between two parties, what's expected of them by the other.
When God established a covenant with Israel, God spelled out to them what's expected of God's covenant partners. The most basic and cherished of these expectations are the Ten Commandments. The Israelites carried around the tablets of the commandments wherever they went. They carried them in a large fancy box known as the "Ark of the Covenant." (see above as well as "Raiders of the Lost Ark")
The covenants of the Bible were not one-sided. God not only set forth expectations from the Israelites, God also let them know what they could expect from their Covenant Partner, the LORD. God promised them blessing, protection, land, redemption and unconditional love. The covenants of the Bible are very similar to the marriage covenant. They establish a loving partnership between God and human beings.
In the Old Testament the concept of sin is based on the covenant. Sin is breaking the covenant, being unfaithful to God, forgetting we're in a loving partnership with God.
Here's a thought: A Covenant = a Testament = a Loving Partnership
Question: How do you see your life lived in partnership with God?
Prayer: Loving God, thank you for your promises and for wanting to live in partnership with me. Help me to live as your Covenant Partner. Amen.
