“It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline? But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons.” Hebrews 12:7-8 LSB https://bible.com/bible/3345/heb.12.7-8.LSB
One of the explanations for the rampant immorality our culture demonstrates is the lack of discipline from the church. The church is the salt of the earth. It is the light of the world. It is the leaven of truth. When the world seems godless and runs increasingly counter to God’s ways, the church must embrace the responsibility of failing to execute its assignment to teach obedience to everything Jesus commanded us. Discipline is inherent to the word disciple. A disciple is a disciplined follower of Jesus who seeks to do everything He has commanded us. Why do we need discipline? The body in which we dwell is an enemy of God, for it is inherently rebellious against the ways of God. We see this blatantly in the toddler, who refuses to obey those who love him so dearly but for no reason refuses parental compliance. We need discipline against this flesh that covets and lusts for those things that hinder the spirit. We need discipline to engage the work of God instead of accumulating more things to fill our ever-expanding barns. We need discipline to seek and save the lost who are unlovely, challenging, and often unresponsive to our love until the Holy Spirit breaks through their hearts, leading them to salvation. Parents must teach discipline to their children, using the rod of correction to train them to gain control of their will and emotions. This failure to train our youth biblically is why we have so many young adults today disobedient to God’s ways, for they are without the discipline to either know Him or carry out His commands.
