Jesus spoke in parables so that some would hear but not understand.
Jesus explained the parables to His apostles.
Jesus told His apostles to go out into all the world and make disciples of all nations.
Paul explained Jesus, His examples and His teachings in great detail for all to understand.
Jesus and Paul are recorded in the Bible.
The whole Bible is read by many millions today.
John 8:31 and 32
If you abide in My (Jesus) word, then you are truly disciples of Mine; 32 and you shall know the truth, and the truth shall make you free.
