A short while back we celebrated the feast of Corpus Christi right after Trinity Sunday. (This year on June 10th.) The liturgists have changed the title to the "Solemnity of the Most Holy Body and Blood of Christ." I liked the old title better. In any case the scripture readings are about the sealing of a covenant in a sacrifice of blood. A covenant can mean a will or an agreement (treaty).
I ask: why would the Lord care for me enough to want to enter into an agreement with me, especially one which is unbreakable (on God's part)? Who am I that God should care? How can I possibly enter into an agreement knowing that I will fall short on my side? With grace, I can get to the point of admitting my faults and accepting God's care for me. Since i am in the care of God, in can consider entering. This is followed by a recognition that I will fail to fulfill my part of the agreement. I can trust in God's help in keeping my side of the bargain.
Perhaps my best response will be from two of the stanza's from the Psalm for the day - Psalm 116
LORD, I am your servant,
your servant, the child of your maidservant;
you have loosed my bonds.
I will offer a sacrifice of praise
and call on the name of the LORD.
In my eyes this may not be enough, yet in faith I know that it will suffice.
