Children simply trust and rely on their parents. They regard their parents as the highest authority and suppose them always right so they are simply obedient to their parents. God is our Father in Heaven and He is truly the utmost and righteous one. We should rely totally on Him and simply obedient to Him. 

Children are pure and simple. They live in the guide of their hearts, while adults their interests. To increase myself to go back to the style of a child, I will pray to the Lord and ask for it. Meanwhile, I must train myself by recollecting my heart while in childhood and observing children around and feeling their hearts. In short, I must learn from children.

God set up the marriage to protect the joint of a man and a woman. God created both male and female and wanted them to help each other in every way in their lives, and also give them the explicit statement in this close relationship. Hence, God is willing to see us finding "the other part" of us and join with him/her. Everyone of us should be serious and prudential in our marriage, which is the most important choice in our lives. Careless and thoughtless marriages are mistakes, which we must avoid. A man must protect his wife and so does a woman.

Jesus offers us himself as our Counselor of marriage. A struggling couple needs to think about Jesus' love and guide so as to discern mistakes of each and opinions around.
