Principles for Understanding the Law (1)

layers Part 15 of 16 menu_book More on Matthew lightbulb 10 illustrations in this sermon

Pastor Albert N. Martin begins a series on the Ten Commandments by establishing foundational principles for their proper understanding, preaching, and application. He expounds Matthew 5:21-30, demonstrating that God's law extends to every faculty of human nature—thoughts, desires, and words, not just external actions. Furthermore, he argues that when a sin is forbidden, the opposite duty is commanded, and vice versa. Martin applies these principles to both the unconverted, urging them to recognize their profound sinfulness and need for Christ, and to believers, calling them to deeper self-examination, penitence, and appreciation for Christ's perfect obedience.

Key Quotes

“But positively stated, it is our goal that with reference to the Christian life, we may together, pursue an increasingly accurate education of our consciences, that we may further pursue an increasing measure of the spirit of genuine penitence, watchfulness, in conjunction with our own remaining sin, and that we may pursue greater measures of felt dependence upon Christ, both as the only ground of our acceptance before God, and also as the only source of power to live a life that is well-pleasing to God according to the directives of His law.”
“For the more we understand of the demands of the law, and realize that our Lord Jesus before all of those demands was utterly without sin, the more we should appreciate the glory of His sinlessness, and the more we see of the breadth of the law, and all of the sins in us which it exposes, then the more we should appreciate His vicarious sin-bearing, His vicarious curse-bearing.”
“It goes as deep as the most hidden, deeply embedded springs of our being, as well as extends to the broadest streams of the patterns of our visible and external actions.”
“Why? Because we have broken the commandment as God intended the commandment to regulate every faculty of our humanity.”
“I trust from these two examples of our Lord, your judgment is persuaded that when I state that one of the rules that will guide us in working in the kingdom of God, in working through the Ten Commandments, is this rule that the sins forbidden and the duties commanded in the Decalogue extend to every faculty of our humanity, that this is not some arbitrary principle picked up by evangelical or Puritan or Reformed tradition, but it's one that grows out of the very words of the Son of God, the infallible interpreter of the significance and meaning of the law of God.”
“The first springs of that which rises out of the man, the imagination of the thoughts of his heart was only evil continually.”
“Not once, not once, in one area, did he deflect one ten-thousandth of an inch from the perfect rectitude of God's holy law.”
“My unconverted friend, you live on the edge of eternal destruction to live another day without the covering of the blood and righteousness of Christ.”

Applications

The unconverted

  • Understand and feel your desperate need of Christ and His salvation by the Spirit attending the preaching of the law.
  • Look away from yourself to the perfect obedience of Christ, who fulfilled the law in its precepts and penalties.
  • Recognize that you are a bad sinner and need a Savior, and that wrath is indeed coming, because you have failed to recognize the law's full breadth.
  • Recognize that every sin forbidden and duty commanded extends to every faculty of your humanity, including your heart's affections, making you an idolater if you have inordinate attachments.
  • Recognize that if the first commandment forbids other gods, it commands that the one true God be your God, loved and served with all your heart, mind, soul, and strength.
  • Recognize that 'you shall not murder' demands that you do all in your power to maintain loving, amicable relationships with all fellow human beings.
  • Flee to Christ and Christ alone for a just pardon and covering for all your sins, from the deepest secret sins to visible ones, because you are an unforgiven, uncleansed sinner under the broad measure of God's holy law.

All listeners

  • Pursue an increasingly accurate education of your consciences, an increasing measure of genuine penitence and watchfulness over remaining sin, and greater felt dependence on Christ as the ground of acceptance and source of power.
  • See with renewed understanding and deeper appreciation the extent of the sinlessness of our Lord Jesus, and His vicarious sin-bearing.
  • Pray that God, by His Holy Spirit, will take His holy law and bring it to bear upon the deepest hidden springs of your internal existence, as well as the broadest streams of your external life.
  • Pray the psalmist's prayer: 'Search me, O God, and know my heart; try me and know my thoughts. See if there be any wicked way in me, and lead me in the way everlasting.'
  • Cultivate a new level of appreciation and love for the Lord Jesus as the sinless one, keeping in mind His perfect obedience to the law.
  • Out of gratitude to Christ, desire that the principle of the law by which He lived would be the principle with which you live, seeking to respect negative injunctions and work out opposite virtues in the strength of Christ and power of the Spirit.
  • Allow your consciences to be open to every impress of the law, leading you to see your duty, discover your sin, flee afresh to Christ, see His perfect obedience, trust in Him, and look to Him for grace and strength to live a life well-pleasing to God.
  • Pray that God will take His holy law and bring to some hearts a felt knowledge of sin, leading them to flee to Christ for pardon.
  • Welcome God's law into every nook and cranny of your lives, earnestly pleading, 'Search me, O God, and know my heart; Try me and know my thoughts. See if there be any wicked way in me, and lead me in the way everlasting.'
