Isaiah 58 and Mark 2 confront the same problem: spiritual legalism that is content with religious performance but lacks the substance of faith. Israel fasted, humbled themselves outwardly, and acted like they delighted to draw near to God, yet their hearts were far from him. God did not receive their fasting because it was joined to oppression, quarreling, self-interest, and pride. The fast God chooses loosens bonds of wickedness, serves the hungry, cares for the afflicted, and walks in true righteousness.
Mark presents John’s disciples and the Pharisees as questioning Christ because his disciples do not keep their made-up fasting rules. Their question puts them in the place of judge over the King of glory. Spiritual pride always overestimates its own excellence, whether it claims a righteousness of its own, imagines that God’s favor was deserved, boasts in a righteousness it does not possess, or elevates itself by pushing somebody else down.
Jesus answers with the picture of the bridegroom. Fasting is a discipline of denial and longing, but the Messiah for whom they longed was standing right in front of them. The coming of the bridegroom is a time for feasting, not fasting. Jesus identifies himself as the bridegroom of God’s people, a title belonging to Yahweh in the Old Testament, and as the bridegroom who will be taken away in suffering and death. The suffering servant and the divine husband of God’s people are one person: Jesus Christ, altogether God and altogether man.
Jesus’ images of unshrunk cloth and new wine make clear that the gospel cannot be added on to an old life. Christ does not come to patch up self-righteousness or pour the new covenant into an unregenerate heart. The old must pass away for the new to come. Christ clothes his people in his righteousness and washes them clean in the blood of the Lamb, but sinners must be born again, repent of their sins, and trust him rather than trying to mix his righteousness with their own filthy rags.
Fasting still has a place between Christ’s first coming and his return, but it must be done with a humble heart before God, not for the eyes of others. The call is to choose the real thing over the performative. God is not after religious posts, visible habits, or the appearance of holiness. God is after a heart made new by the Spirit, producing true humility, justice, mercy, kindness, love, joy, and righteousness.

Key Takeaways
- 1. Choose substance over religious performance. Spiritual performance can make a person look righteous while leaving the heart untouched. Prayer, fasting, church attendance, and Bible reading become dangerous when they are used to build an image rather than cultivate communion with God. God cares about actual righteousness, not the appearance of it. [25:08]
- 2. Christ is the bridegroom of God’s people. Jesus does not merely answer a question about fasting. His words announce that Yahweh has come near to restore his people, and that the bridegroom will be taken away in suffering for their sins. The joy of his presence and the sorrow of his death both reveal who he is. [15:21]
- 3. The gospel cannot be an add-on. New wine does not fit inside old wineskins, and Christ’s righteousness cannot be mixed with self-righteousness. The new covenant requires more than improved habits or religious association. The old must pass away because sinners must be made new from above. [21:41]
- 4. Fasting should express humble longing. Fasting is not a badge of discipline or a way to gain the notice of other people. Fasting denies the flesh in order to train the heart to long for the greater good found in Christ. The Father sees what is done in secret and receives humble devotion. [24:03]
- 5. True righteousness serves the afflicted. Isaiah’s chosen fast breaks yokes, feeds the hungry, covers the naked, and refuses the pride that points fingers at others. A transformed heart does not merely avoid public sin but pours itself out for those in need. God’s righteousness bears visible fruit in mercy and justice.
