One of the surest signs that you are maturing in the Lord and gaining wisdom is by seeing how you are resounding to discipline and correction in your life. Correction is something no one takes easily. First of all it requires that we admit that we are wrong. This requires humility. This is a character trait that is not abounding in our lives since the fall. This is why we are told here not to reject the discipline of God. We are told this because we are likely to just reject discipline automatically. One of the most important lessons I ever received from the man who disciples me was that I needed to consider it kindness when a godly man rebuked me. He taught me to take a moment and consider what was said to me rather than just rejecting it out of hand. Some of the best lessons I've ever learned were due to the rebuke of a godly person who loved me enough to speak the truth to me when I needed it most.
We are also told here not to loathe God's reproof. The only reason I loathe reproof is because of the pride in my heart that makes me think I am always right. You would think I would be delighted for God, Who cannot err, to correct me and keep me from making mistakes that could harm me. Unfortunately I annuli fled with pride and foolishness to listen to Him and actually choose being wrong rather than admitting to my error and learning from Him.
Solomon has the wisdom here to appeal to his son from a human standpoint. He tells his own son that God reproves and disciplines those He loves. ThenLord doesn't discipline us out of some power trip. He does this because He loves us. Remember that the next time you are being disciplined. God is working this way in your life because He loves you. This verse it quoted in Hebrews 12 and we are informed that God is disciplining us because He wants us to share in His holiness. God is incapable of acting wrongly and therefore we need to see that even His discipline is for our ultimate good.
The final words that Solomon offers to his son are supposed to remind him that earthly fathers discipline thir sons because they delight in them. A father looks at his son and sees the potential of what he catn be. As he disciplines the child, it is only in hope of what his child can become if he ultimately follows the Lord with all of His heart. The father takes delight in his son or daughter as he or she walks with the Lord. Disciplne and correction is the way of life itself. If we learn how to receive it from God and from those He sends to us we will be blessed greatly. So learn to receive discipline and correction, especially from God. He loves you and only is working toward your best interests when He does.
