“This is the principal purpose of the Law and its most valuable contribution. As long as a person is not a murderer, adulterer, thief, he would swear that he is righteous. How is God going to humble such a person except by the Law? The Law is the hammer of death, the thunder of hell, and the lightning of God’s wrath to bring down the proud and shameless hypocrites. When the Law was instituted on Mount Sinai it was accompanied by lightning, by storms, by the sound of trumpets, to tear to pieces that monster called self-righteousness. As long as a person thinks he is right he is going to be incomprehensibly proud and pre- sumptuous. He is going to hate God, despise His grace and mercy, and ignore the promises in Christ. The Gospel of the free forgiveness of sins through Christ will never appeal to the self-righteous.” Martin Luther
This sums of the purpose of the law well. Why was God’s law given, or of what use is God’s law today? It is to humble the sinner so they might see the need for Christ. The law can by no means make us righteous, but it’s main purpose is to show us our sin, our unrighteousness, our corruption and our guilt before God.
Does Lost Mankind Already Know they are Sinners?
“This only I want to learn from you: Did you receive the Spirit by the works of the law, or by the hearing of faith? 3 Are you so foolish? Having begun in the Spirit, are you now being made perfect by the flesh? 4 Have you suffered so many things in vain—if indeed it was in vain? Therefore He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?— 6 just as Abraham “believed God, and it was accounted to him for righteousness.” Galatians 3:2-6
Is it paying tithes? Giving offerings? Reading the Bible, going to church? Being nice to people? Sharing the gospel with others? Wearing a suit and tie to church? Taking communion? Getting water baptized? Coming forward for prayer after service? Will these cause God to move in your life, fill you with His Spirit and work miracles in your life?
Galatians 2:18-19 NASB
For if I rebuild what I have once destroyed, I prove myself to be a transgressor. For through the Law I died to the Law, so that I might live to God.
Instead of living that faith in Christ was the highest and greatest thing we could do to please God and only thing we could do to be more acceptable to Him, Peter began to go back under the law of sin and death.
As Christians we must never try to rebuild what what we tore down when we believed the gospel. We tore down a corrupt system of blessings and favor based upon doing and striving to earn. We must not leave faith to go back to rebuild this system that leads to sin and death.
“For am I now seeking the favor of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a bond-servant of Christ.” Gal. 1:10
Too many times ministers can be people pleasers from the pulpits. This leads to only compromise, spiritual immaturity or worse, false converts. The shepherd of the flock must have the interests of the sheep at hand, even at their own inconvenience or discomfort. When he sees danger ahead and begins to sharply and aggressively strike the sheep with his rod to get them to move away from the danger, he does so out of love.
