How to study the Bible
One would not be able to differentiate at the beginning which part of the Bible is a parable and which part is not a parable. Unless it is a direct commandment from God as the Ten Commandments are, it is always wise to treat every other word in the Bible from the Prophets as a parable. One would also require an Electronic Bible so that key words from the Bible can be searched and grouped together therefore one can refer between verses to further understand the meanings of them.
MT 13:34 Jesus spoke all these things to the crowd in parables; he did not say anything to them without using a parable. 35 So was fulfilled what was spoken through the prophet:
"I will open my mouth in parables,
I will utter things hidden since the creation of the world."
MK 4:13 Then Jesus said to them, "Don't you understand this parable? How then will you understand any parable?
MK 4:33 With many similar parables Jesus spoke the word to them, as much as they could understand. 34 He did not say anything to them without using a parable. But when he was alone with his own disciples, he explained everything.
LK 8:4 While a large crowd was gathering and people were coming to Jesus from town after town, he told this parable: 5 "A farmer went out to sow his seed. As he was scattering the seed, some fell along the path; it was trampled on, and the birds of the air ate it up. 6 Some fell on rock, and when it came up, the plants withered because they had no moisture. 7 Other seed fell among thorns, which grew up with it and choked the plants. 8 Still other seed fell on good soil. It came up and yielded a crop, a hundred times more than was sown."
When he said this, he called out, "He who has ears to hear, let him hear."
LK 8:9 His disciples asked him what this parable meant. 10 He said, "The knowledge of the secrets of the kingdom of God has been given to you, but to others I speak in parables, so that,
" `though seeing, they may not see;
though hearing, they may not understand.'
LK 8:11 "This is the meaning of the parable: The seed is the word of God. 12 Those along the path are the ones who hear, and then the devil comes and takes away the word from their hearts, so that they may not believe and be saved. 13 Those on the rock are the ones who receive the word with joy when they hear it, but they have no root. They believe for a while, but in the time of testing they fall away. 14 The seed that fell among thorns stands for those who hear, but as they go on their way they are choked by life's worries, riches and pleasures, and they do not mature. 15 But the seed on good soil stands for those with a noble and good heart, who hear the word, retain it, and by persevering produce a crop.
LK 8:16 "No one lights a lamp and hides it in a jar or puts it under a bed. Instead, he puts it on a stand, so that those who come in can see the light. 17 For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open. 18 Therefore consider carefully how you listen. Whoever has will be given more; whoever does not have, even what he thinks he has will be taken from him."
Remember that the Bible is full of metaphors within metaphors, one would have to see through them by understanding of experience through knowledge.
