He has made us competent as ministers of a new covenant - not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.
Thoughts on today's verse
A new covenant -- God willingly entered into a new agreement with us, his creatures, sealed it with the blood of his Son Jesus, and sent the Spirit to give us the power to live the life of this new covenant. God has made a covenant of love and grace with us. The Almighty has then turned around and made us worthy and competent to share that covenant with others. Now wonder it is life-giving: it brings life to us and through us!
O holy and majestic God, thank you for your grace that has saved me from sin and has redeemed me from the law of sin and death. Thank you for sending the gift of your Son and the gift of your Spirit so that I can live with you in a covenant of life, grace, and love. While I confess my weaknesses, I also promise you that I will live to honor your sacrifice, love and covenant, trusting that you will ultimately empower me to be what you are calling me to be. In Jesus name I pray. Amen.
