Parables. Probably you have heard these in your Sunday schools or read such when you have your daily devotions. Jesus Christ used these as His device to spread the word of God. Examples of parables include The Lost Sheep, The Prodigal Son and The Good Samaritan.
The parables are very intimate to His listeners back then as He told stories that are set in the agricultural first century life. Grand things such as the Kingdom of God were alluded in the characters’ everyday lives, making these very effective in teaching His lessons. You must note that parables normally teach a lesson or two. Overthinking will only make you lose its central point.
