2 Corinthians 3:6 who has made us competent to be ministers of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life.
Trying to keep up with every rule and restriction can be tiresome and in the end doesn’t bring about perfection anyway. We’re unable to keep the whole law and that’s why we have it. The law shows us that we are imperfect and in need of a savior. In Christ we have that Savior and a new covenant, one not dependent on rule-keeping, but on grace.
Trying to reconcile with God based on following the rules and doing good will still result in death. We cant’ reach God in this way. Only through the grace of Christ do we have a chance at a right relationship with God. Now He’s made us ministers of that new covenant. He’s shown us grace and now we’re to show grace on His behalf.
The Holy Spirit works in us to show the life-giving grace of God to others through our lives. Because we’ve been forgiven, we are empowered to forgive. Because we’ve been shown love, we are able to show love. Only with the help of the Holy Spirit are we competent to minister to others in this way.
