Jesus' Teaching on Law in Relation to Grace and Mercy
Jesus' teaching on the law cannot be separated from his embodiment of grace and mercy, yet he never positioned these realities in opposition. John's Gospel declares that "the law was given through Moses. Grace and truth were realized through Jesus Christ" [1]. This statement does not pit law against grace but establishes a progression: the law revealed God's righteousness, while Christ fulfilled and embodied both grace and truth in his person and work.
The Law as Revelation of God's Character
The law reflects God's own nature. His righteousness is "part of his character" and described as "everlasting" and "enduring for ever" [3]. This righteousness is "exhibited in His testimonies...His commandments...His judgments...His word...His ways...His acts" [3]. The law, therefore, is not arbitrary legislation but the expression of divine perfection. Righteousness itself "is obedience to God's law" [2], and Christ "fulfilled all" righteousness [2], demonstrating that the law's demands are not abolished but satisfied in him.
Jesus' approach to the law was not to dismantle it but to reveal its true intent. He came as one who "loves" righteousness, was "sustained by" it, and "preached" it [2]. His mission included bringing in "everlasting" righteousness [2], indicating that the law's moral core remains permanent. The law's function is legislative and distributive: God "imposes righteous laws on his creatures and executes them righteously" [4]. Justice is "not an optional product of his will, but an unchangeable principle of his very nature" [4].
Mercy Within the Framework of Justice
Mercy does not negate justice but operates in harmony with it. Mercy's "object is misery" [5], and through Christ's atoning sacrifice, "a way is open for the exercise of mercy towards the sons of men, in harmony with the demands of truth and righteousness" [5]. The psalmist's declaration that "mercy and truth meet together" finds its fulfillment in Christ [5], where divine attributes that might seem contradictory are reconciled.
Jesus taught mercy as both a divine attribute to be imitated and a Christian obligation. Mercy is to be shown "after the example of God" [6] and is "enjoined" upon believers [6]. It should be "engraved on the heart" [6] and is "characteristic of saints" [6]. The scope of mercy extends broadly: "to our brethren," "to those that are in distress," "to the poor," "to backsliders," and even "to animals" [6]. Jesus himself declared the "blessedness of showing" mercy [6], promising that the merciful will receive mercy.
The Interplay of Law and Grace in Jesus' Teaching
Grace "came by Christ" and was "given by Christ" [7], yet this grace does not render the law obsolete. Christ is described as "the end of the law for" righteousness [2], meaning he is its goal and fulfillment, not its termination. The law's purpose includes leading people to "sigh for the grace of Christ" by revealing their inability to meet its demands [9]. For believers, the law continues to function formatively, as "the faithful themselves, who are already endued with the fear of God, may advance more and more in the pursuit of piety" [9].
Jesus' teaching on judgment reflects this integration of law and mercy. He called for an end to oppressive, hypocritical judgment—the "rigorous scrutiny of trivial matters" [8]—while maintaining "clear opposition to sin" [8]. Mercy is "a dominant theme in Jesus' teaching and practice" but "not at the expense of" moral clarity [8]. The principle that "God measures us by our treatment of others" [8] shows that mercy is not sentimentality but a reflection of having received divine mercy.
The Gospel operates as "the law of liberty" [10], which "frees us from the curse of the law, that henceforth we should be free to love and obey willingly" [10]. This law of liberty is "not a law of external constraint, but of internal, free, instinctive inclination" [10]. Yet it remains a law—one that "condemns us still more" if we fail to "practice the law of love to our neighbor" [10]. Jesus thus transforms the law from external demand to internal desire, where grace enables what law requires and mercy flows from those who have been shown mercy.

At the same time, Jesus calls for people to stop oppressively controlling others in the name of pastoral concern. The judgment Jesus prohibits often involves rigorous scrutiny of trivial matters (see 23:23-24). God alone has the right to judge (see Jas 4:11-12). • you will not be judged: This might refer to God’s judgment at the end of history (see Matt 5:7).
