Hi. You have not submitted the essay this question refers to, which makes it impossible for it to be answered. However, I will try and help as best I can.
It is only possible to know how the reference to King Midas is important for the essay if the reading of the essay is done. However, King Midas is known to be a very ambitious and wealth-obsessed King, even to the point of selling his own soul to become richer, which causes him to lose his most precious possession, his daughter. In this case, we can consider that the essay must present this king to draw a parallel between the subject of the essay and this tragic story of Midas, stimulated by the thirst for riches. We can therefore consider that the reference to Midas serves to intensify some of Chesterton's positions within the essay.
This is an example of an allusion, because an allusion is a figure of speech that allows a text to make references to other texts, people, characters, places and external situations.
I am worried that people now days are getting so familiar with God or at least their idea of God that they have lost the respect due, to God Almighty. They view him as little more then a good friend who will understand if they at times don't treat him as the creator of the universe. They have more of a horizontal view of God then a vertical view. This comes from the humanism which has infiltrated even the evangelical church. We have elevated ourselves, by promoting such things as the need for self-esteem in order to understand God's love for us. We no longer focus on his character but on ours. Or we bring him down to our level by teaching that there is a time and place for a person to forgive God for the things we have held against him. "It is no longer sin to hold something against God; it is normal and we should deal with it by letting it go and forgiving him."
