“My part is essential to God’s plan for salvation.“
The text states (par.6):
Today we will attempt to understand joy is our function here. (….) You are God’s messenger today. You bring His happiness to all you look upon; His peace to everyone who looks on you and sees His message in your happy face.
This is the most natural thing imaginable. But you have unlearned it by your focus on other things. Given that situation, returning to the natural state of exuding joy and peace will take a little willingness on your part. You do not have to know how to communicate love and light, you do not have to know when to send out freedom or joy. The only thing needed is a small amount of willingness to let go of old patterns of focus and welcome new ones. That way you create space to allow yourself to direct your attention to the creative stream that is expressing as love and joy, beauty and peace.
They are in you, for they are you. You are perfectly capable of aligning with them in any given situation, because you were created to do just that. Be willing to give up the familiar but limited way of looking at things in return for a glorious vision. It is the exchange of a penny for a fortune. It is the exchange of a dungeon for a spring meadow.
Your part is essential because doing it is the only way to experience the glory of creation in the process of extending. Knock and the door will be opened.
