It seems to you that the Holy Spirit does not produce joy consistently in you only because you do not consistently arouse joy in others. Their reactions to you are your evaluations of His consistency. When you are inconsistent you will not always give rise to joy, and so you will not always recognize His consistency. What you offer to your brother you offer to Him, because He cannot go beyond your offering in His giving. This is not because He limits His giving, but simply because you have limited your receiving. The decision to receive is the decision to accept.T-9.VI.2:1-6
A Course in Miracles (p. 328). Foundation for Inner Peace. Kindle Edition.
One of the paradoxical principles taught by A Course In Miracles is that you learn what you teach. A corollary principle is that you receive what you give. If you would have joy, give joy for it is in the giving that joy is generated. These principles are not the way of the world of the ego but the say of the Spirit.
In Unitarian Universalism some of us join together to affirm and promote the acceptance of one another and the encouragement to spiritual growth. It is in this acceptance and encouragement that joy is manifested.
Today it is suggested that we reflect on what we want to receive and if it is loving, give it.
