To rightly divide the Word of God is to make a straight cut into the Word of God. The man or woman of God must know and live the Word of God so thoroughly that he or she can make a straight cut into the Word, knowing, living and presenting it to others in a straight, truthful and accurate way. One expositor said that our ability to present the word in such a straightforward way will in fact lay a path before us that is as straight as our knowledge of the Word. This path before us becomes the road in which others and we travel upon. If we heed to the exposure brought to us through the Word it will brings us freedom in Christ.
Correction here means to be restored to an upright state resulting in salvation.
Reproof brings exposure of sin. If we heed we start to become free. As we become free the Word of God then starts to restore us to an upright state. This talks about mentoring and discipling and the final release into our ministry. Exposure, restoration, mentoring, and call to ministry.
