Principle of heaven

Unless you accept in your own life the principle of self-sacrificing love, which is the principle of His character, you cannot know God. MB 25
Even His disciples were so blinded by the selfishness of their hearts that they were slow to understand Him who had come to manifest to them the Father’s love. MB 25

Putting this quote and the previous quote together is a sobering combination. Please help me to pull it together in my own mind.
Selfishness blinds my heart from seeing you.
Selfishness sever's my connection with you.
Selfishness makes it impossible to understand the principles of heaven, self-sacrificing love.
Papa Father,
I truly want to know you. I choose to accept into my heart again this morning "the principle of self-sacrificing love ." I am so full of myself that I hardly know what I am asking. I only know that I want it. What ever is the avenue to YOU and YOU alone, I want.
Another thing that I notice in this passage is the word "accept". I cannot strain, stress, and stretch enough or work hard enough for "self sacrificing love"; I can only accept it. Like everything else about YOU, it is a gift that I choose to receive. It is not something that I can find anywhere in the deep recesses of my heart. It simply does not exist and so why strain for something that I do not have? All I can do is choose to accept the gift of love that you offer. That is it. I accept Your gift of love and You place it in my heart. Not only do You place it there but You grow it until it is so big that there is no room for anything else. How cool is that?
