A new article from Center for Action and Contemplation calls and expands upon Lynne Twists’ teachings in the mindset of sufficiency. “When we live in the context of sufficiency, we find a natural freedom and integrity. We engage in life from a sense of our own wholeness rather than a desperate longing to be complete.
As long as we operate inside any scarcity model, there will never be enough God or grace to go around. Jesus came to undo our notions of scarcity and tip us over into a worldview of absolute abundance. The Gospel reveals a divine world of infinity, a worldview of enough and more than enough. The Christian word for this undeserved abundance is “grace.” It is a major mental and heart conversion to move from a scarcity model to an abundance model and to live with an attitude of gratitude. 
Lynne Twist, co-founder of The Pachamama Alliance, writes about the reality of abundance, which she calls “sufficiency,” in her excellent book The Soul of Money. The wisdom below might just nudge you over the line. Read these excerpts with an open mind and heart. Fr Richard Rohr
We each have a choice in any setting to step back and let go of the mind-set of scarcity. Once we let go of scarcity, we discover the surprising truth of sufficiency. By sufficiency, I don’t mean a quantity of anything. . . . Sufficiency isn’t an amount at all. It is an experience, a context we generate, a declaration, a knowing that there is enough and that we are enough. . . .
When we live in the context of sufficiency, we find a natural freedom and integrity. We engage in life from a sense of our own wholeness rather than a desperate longing to be complete. We feel naturally called to share the resources that flow through our lives—our time, our money, our wisdom, our energy, at whatever level those resources flow—to serve our highest commitments. . . .
Sufficiency as a way of being offers us enormous personal freedom and possibility. Rather than scarcity’s myths that tell us that the only way to perceive the world is there’s not enough, more is better, and that’s just the way it is, the truth of sufficiency asserts that there is enough for everyone. Knowing there is enough inspires sharing, collaboration, and contribution. . . .
Grounded in sufficiency, money’s movement in and out of our life feels natural. We can see that flow as healthy and true and allow that movement instead of being anxious about it or hoarding. In sufficiency, we recognize and celebrate money’s power for good—our power to do good with it—and we can experience fulfillment in directing the flow toward our highest ideals and commitments. When we perceive the world as one in which there is enough and we are enough to make the world work for everyone everywhere, with no one left out, our money carries that energy and generates relationships and partnerships in which everyone feels able and valued, regardless of their economic circumstances. . . .
No matter how much or how little money you have flowing through your life, when you direct that flow with soulful purpose, you feel wealthy. You feel vibrant and alive when you use your money in a way that represents you, not just as a response to the market economy, but also as an expression of who you are.
