The parable is about the kingdom of Heaven, Jesus said the kingdom is inside of us(his true disciples). What was inside of his disciples? His word. Jesus Himself was a humble man, showing us an example to follow. He existed before we were all created, the Word was with God in the beginning, the Word was God. The Word dwelt in the flesh and was so humble, more humble than any man, because of that, he was exalted to sit beside the highest. The parable has connection with the sower and the seed, the seed can be related to the mustard seed, and He interpeted the seed to be the word of God. Jesus is the bread of life, and whoever eats his flesh, has eternal life. But bread must come from wheat, from a seed. And water must feed the seed. And people must tend and labour for the harvest. We must tend to the word of God, not only hear it, but do it, not be a slothful servant(proverbs talk about slothful servants, they are overcome with thorns and tares). When we tend to it, it grows, the word of God increases(the bible talks about this, I wont tell where the exact scriptures are, you\'ll have to work for that yourself) inside of us,(Jesus said one must be born of water and Spirit to inherit eternal life) the word of God is like water, washing our conscience(so we have a new conscience, born to abstain from all sin) so we can be baptised and then baptised with the Holy Spirit, born of Spirit. But before that we labour for the word to grow so the birds of the air with nest in it(the Spirit of God, there are gifts of the Spirit, working miracles, speaking differant languages, prophecy, revelation, faith, knowledge and wisdom), be not deceived, Paul said that everyone attending to the TRUE church of God, will and has to bring these things to every gathering. 1 Corinthians 14:26 - How is it then, brethren? when ye come together, EVERY ONE of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.\" Most of these so called churches are worshipping in vain if the gospel is not preached with power also, not with wisdom of words, lest the cross have no effect. 1 Corinthians 1:17 - For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.\" 1 Corinthians 2:4 - And my speech and my preaching was not with enticing words of man\'s wisdom, but in demonstration of the Spirit and of power:\" Hebrews 4:12 - For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.\" 1 Corinthians 4:20 - For the kingdom of God is not in word, but in power.\" 1 Thessalonians 1:5 - For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.\" 2 Thessalonians 1:11 - Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfil all the good pleasure of his goodness, and the work of faith with power:\" 2 Peter 1:3 - According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:\" 2 Corinthians 3:6 - Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.\"
