Three Loaves - Explanation 

Jesus Christ is not the Image of word alone, but the Image of invisible trinity God, that means in Jesus Christ we can see our Heavenly Father (I and the Father are one - John 10:30), and the Son (He who came down from heaven, that is, the Son of Man who is in heaven - John 3:13), and the Holy Spirit (if I do not go away, the Helper will not come to you - John 16:7).

Why Jesus Christ spoke about the story of three loaves?

And he said to them, Which of you who has a friend will go to him at midnight and say to him, Friend, lend me three loaves, for a friend of mine has arrived on a journey, and I have nothing to set before him; and he will answer from within, Do not bother me; the door is now shut, and my children are with me in bed. I cannot get up and give you anything? I tell you, though he will not get up and give him anything because he is his friend, yet because of his impudence he will rise and give him whatever he needs - Luke 11:5-8

Because he is the image of Trinity God

Apostle John mentioned Trinity God as Father, Word and Holy Spirit - because there are three who are testifying in Heaven: the Father, the Word, and the Holy Spirit, and these three are one -  1 John 5:7

And as a single person, Son Jesus Christ is representing all three (Father, Word and Holy Spirit) - and there are three who are testifying in the earth: the Spirit, and the water, and the blood, and the three are into the one - 1 John 5:8
