Maybe your ambition is to be described in somewhat more glowing terms than 'a competent minister'. But that's Paul's claim for himself and his companions (2 Cor. 3:4-6). I wonder what comes to mind when you think of that phrase: someone who can preach an ok sermon, has a good bedside manner for hospital visiting and feels at ease with young people? A competent minister.
I think Paul might be claiming something different and something more. He speaks about them being made competent (notice the source of the competency) "as ministers of a new covenant - not of the letter but of the Spirit; for the letter kills, but the Spirit gives life."
There is a real need for those who handle God's Word to know how to handle the transition from old to new covenant and what that means for those called to live as followers of Jesus. It isn't a sermonising skill - far from it; it is broader and deeper. It's being able to navigate waters of interpretation and application that honour Christ and the Spirit, that breathes life and vitality and newness, that addresses life in the Spirit in the here and now. That doesn't mean it's about how you handle the charismatic issue (that would be a shallow conclusion), but how we promote and cultivate and teach a life that is built on the reality that "Christ is the end of the law" (Rom. 10:4) and that radiates the glory of the new covenant (2 Cor. 312ff).
Perhaps your prayer - like mine - is to be made competent, knowing how demanding the task is and not claiming anything special for ourselves.
