10 For our earthly fathers disciplined us for only a short time as seemed best to them; but He disciplines us for our good, so that we may share His holiness. 11 For the time being no discipline brings joy, but seems sad and painful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness [right standing with God and a lifestyle and attitude that seeks conformity to God’s will and purpose].
12 So then, strengthen hands that are weak and knees that tremble.13 Cut through and make smooth, straight paths for your feet [that are safe and go in the right direction], so that the leg which is lame may not be put out of joint, but rather may be healed.
Discipline and correction are not very pleasant things, but they are necessary if we are to grow and remain on the path that God has set for us. Correction is a process that rectifies error or inaccuracies meaning the purpose of correction is restoration and not destruction. The joy and benefit of discipline and correction are not felt when it is being administered but later on the fruits of it are seen and enjoyed.
You and I are to subject ourselves to correction for the purpose of discipline for if we do not do so then it means that we are illegitimate because every father disciplines his children and if we are Gods children then we should expect to be disciplined.
The correction and discipline that we go through strengthens our hands and knees so that they no longer tremble then we are able to cut through the straight paths that are safe and moving in the right direction. Through correction and discipline the leg that was lame is not put out of joint but rather it is healed and strengthened able to walk again.
Do not resist nor run away from correction from the Lord. Humble yourself and subject yourself to the process because it is for your own good to keep you in the straight and narrow.
