Mark 4:2-12

And He taught them many things in parables, and in His teaching He said to them, “Listen! A sower went out to sow seed; and as he was sowing, some seed fell by the road, and the birds came and ate it up. Other seed fell on rocks where there was not much soil; and immediately a plant sprang up because the soil had no depth. And when the sun came up, the plant was scorched; and because it had no root, it dried up and withered away. Other seed fell among thorns, and the thorns came up and choked it, and it yielded no grain. And other seed fell into good soil, and as the plants grew and increased, they yielded a crop and produced thirty, sixty, and a hundred times [as much as had been sown].” And He said, “He who has ears to hear, let him hear and heed My words.” As soon as He was alone, those who were around Him, together with the twelve [disciples], began asking Him about [the interpretation of] the parables. He said to them, “The mystery of the kingdom of God has been given to you [who have teachable hearts], but those who are outside [the unbelievers, the spiritually blind] get everything in parables, so that THEY WILL CONTINUALLY LOOK BUT NOT SEE, AND THEY WILL CONTINUALLY HEAR BUT NOT UNDERSTAND, OTHERWISE THEY MIGHT TURN [from their rejection of the truth] AND BE FORGIVEN.” [Is 6:9, 10; Matt 13:11-15]
