Being transformed into the image of the Son of God does not depend on me.
Thank the Lord for that.
There are things about Christian service that can be learned. Skill sets can be developed. Techniques can be applied. Practice sometimes makes perfect. I could, for instance, wholly apart from the Spirit of God, acquire a greater understanding of Hebrew and Greek through diligent study and as a consequence become a more accurate Bible teacher.
Whether much of eternal value would come from that apart from the Spirit of God is a separate question, but it can certainly be done.
