Question
What are the parables of Jesus? (what a parable is, why He used them, and the major ones)
Analysis
Why Jesus taught in parables
Jesus deliberately taught this way. When His disciples asked why, He said parables both reveal and conceal: to those open to Him they unlock 'the secrets of the kingdom,' but to the hardened they remain a riddle, 'seeing they do not see' (Matthew 13:10–Matthew 13:13, quoting Isaiah 6:9; Isaiah 6:10). Mark notes that He taught the crowds only in parables, then explained everything privately to His disciples (Mark 4:33; Mark 4:34). A parable makes the listener work, and so exposes whether the heart is willing.
The kingdom parables
A large cluster pictures the kingdom of heaven: it starts small and grows vast (the mustard seed, Matthew 13:31–Matthew 13:32), works quietly and pervasively (the leaven, Matthew 13:33), is worth everything you have (the hidden treasure and the pearl, Matthew 13:44–Matthew 13:46), and grows good and bad together until a final sorting (the wheat and weeds, Matthew 13:24–Matthew 13:30). Others warn about readiness and judgment, the sheep and the goats (Matthew 25:31–Matthew 25:46) and the ten virgins (Matthew 25:1–Matthew 25:13).
The grace-and-mercy parables
Luke preserves the most beloved stories of God's mercy. The Prodigal Son shows a father who runs to a returning sinner (Luke 15:20); the Lost Sheep and Lost Coin picture heaven's joy over one who repents (Luke 15:7; Luke 15:10); the Good Samaritan redefines 'neighbor' as anyone in need, even an enemy (Luke 10:36; Luke 10:37); and the Pharisee and the Tax Collector teaches that God justifies the humble, not the self-righteous (Luke 18:9–Luke 18:14). The Rich Fool warns against storing up treasure for yourself but being 'not rich toward God' (Luke 12:16–Luke 12:21).
