5: And he said unto them, Which of you shall have a friend, and shall go unto him at midnight, and say unto him, Friend, lend me three loaves; 6: For a friend of mine in his journey is come to me, and I have nothing to set before him? 7: And he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee. 8: I say unto you, Though he will not rise and give him, because he is his friend, yet because of his importunity he will rise and give him as many as he needeth.

The word “Friend” is mentioned 4 times, so Friendship is the main subject. There are three individuals mentioned in the parable: the person who has a friend come to visit; and that same person who has another Friend (the Lord). So there are two different relationships involved. The problem in the parable is Spiritual Hunger. The person wants to share bread (the Word) with his friend, but he does not have any. The person knows where to get bread so he asks his Friend (the Lord) for bread (the Word) to share with his friend. In order to share with his friend in his journey he must have a good relationship with his Friend (the Lord) who has the bread (the Word) so that he will have bread (spiritual food) given to him so that he can then share
A person must have a relationship with his heavenly friend (Jesus – the Word) so that he can share truth with his earthly friend on his journey of life. There is a third relationship mentioned in the parable. That is the relationship between the Friend (the Lord) and his children, who are with him in bed. This is a different kind of relationship. To be in bed with someone implies an intimate or special relationship. The Friend is the Lord and his children represent His People or His Family. The person outside the door is a friend but he does not have the same relationship as those inside the door who are in bed with their Father (the Lord). The Father (the Lord) and his children (the Family of God) are resting together (in bed). The person outside the door is not resting with the Father (the Lord).
The bed or place of rest represents the place where God or the father rests. The only place in the Bible that mentions God resting is when the 7^th Day Sabbath is mentioned. Example, Hebrews 4:4 For He spake in a certain place of the seventh day on this wise, and God did rest the seventh day from all His works. Also Exodus 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it. We know that God does not need to rest physically, so His resting is clearly to show a spiritual relationship with those who are resting with Him in bed. Thus the bed or resting place represents the 7^th day Sabbath of God, which is used in the parable to show a special relationship that God has with those who keep His 7^th Day Sabbath holy. They are part of His Family.
The door in the parable separates those who are not part of God’s Family from those who are part of God’s Family. In the Bible, Jesus said that He is the Door. John 10:9 I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. This shows that to be saved or to be part of God’s Family, we must go through the door or through Jesus to become part of God’s Family. In the parable the door is shut to those who are not in bed with the Father. Thus Jesus (the Door) wants those outside the door to enter in through Him and to get in bed with His father or to keep the Sabbath Day holy.
