I have always read this with thought that Paul is talking about the kindling afresh of a specific ministry gift: teaching, prophesy, etc. But today, as I look more closely at the original language, I realize Paul is talking about the gift of receiving the Spirit Himself, with the entire ministry of that God-Presence in me and you as in Timothy.
Thus, Paul is saying, kindle afresh the “gift of God” – the work of the Spirit who gifts us with grace (spiritual power) to do all God calls us to, without fear: that work of God that pours forth in response to our faith to believe in, trust in, and obey God.
Kindling that relationship afresh requires our constant and consistent work of surrender to the work of the Spirit in us. It is seeking God’s revelation for ways we quench the work of God’s Spirit in us and sincere repentance for those practices. Following that is constant effort to not quench Spirit’s influence and function within us, realizing that He is the unifying work of God that makes us one with Father and Son. It is constant feeding of-on relationship with the living, breathing, life giving Spirit, who imparts to us the power, provision, ability, specific gifting, & successful ministry of God in us. Kindle afresh our Spirit union.
Father God, thank You. Please reveal to me habits that quench Your freedom to work Your power in me. Forgive me and kindle afresh Your Spirit ministry and reign in me. In Jesus, amen.
