This Verse highlights the impartial essence of the Bible. It does not say “some of the scriptures” but it says “All scripture”.
The Bible does not give us all encouragement alone that we would like to hear but it does discourage us–it discourages us from walking in the flesh through reproof and correction.
Reproof is an expression of disapproval and correction is a process of setting something right.
Definitely, the more that we read our Bible the more that we get to discover the truth which transforms us. I hope that we don’t only choose and pick books that we like to read but pursue to seek the truth and live for Christ–even as we disagree and correct others and ourselves.
Through Reproof and correction, let us not become shameful but become grateful that everyday we get to learn the right things, deny ourselves and live for the Glory that belongs to God.
So, if ever there’s a need to disagree with someone and correct them–go back to the word because it holds the truth, the truth that will lead people to righteousness. As you know the truth, live it and do not be afraid to share it with others with love and mercy.
