But no one who is not moved by the Holy Spirit will seek to enlist in God's army. The carnal man believe all of the Bible is folly, and his nature will prevent his free will from enlisting. It requires the Spirit to act in us to believe. We are adopted and grafted (essentially drafted) in to God's army. Our movement in that direction appear to be of our own doing, because our nature is changed by the Spirit.
Luke 12:8 And I say to you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God.
That's not a draft notice. In addition, if being grafted in has nothing to do with our having free will, then Scripture here
Romans 11:21 For if God hath not spared the natural branches, fear lest perhaps he also spare not thee.
Romans 11:22 See then the goodness and the severity of God: towards them indeed that are fallen, the severity; but towards thee, the goodness of God,if thou abide in goodness, otherwise thou also shalt be cut off.
is saying that Christ takes some people for a test drive, decides not to keep them, then cuts us off.
