From Rigid to Resilient: Seven Biblical Processes That Mirror ACT
The "He Must Increase Model" Explained

Research has revealed that psychological rigidity is linked to, and can predict, mental and emotional health issues, while psychological flexibility is associated with better mental and emotional health (Bond & Bunce, 2003; Bond et al., 2011; Hayes, Strosahl, et al., 2004; Hayes, Wilson, et al., 1996; Kashdan et al., 2006; Kashdan & Rottenberg, 2010; Ruiz, 2010). Acceptance and Commitment Therapy (ACT) describes psychological flexibility through six interrelated processes (Hayes, Luoma, et al., 2006), several of which research supports as active ingredients of change (Levin et al., 2012), often grouped into three broader capacities: open, aware, and active (Hayes, Villatte, et al., 2011).
Did I lose you yet? Hang in there, because the rest gets much easier to understand. When I was initially taught the six processes of ACT, my theology brain kicked in, and all I could hear were biblical principles. Upon further study of Scripture and years of walking through these principles with clients, I recognized seven basic biblical processes that every child of God is instructed to embrace.
Seven Spiritual Processes (with the correlating ACT process in parentheses)
Embrace the Sovereignty of God (Acceptance)
Embrace the Grace of God (Acceptance)
Embrace the Presence of God (Present-Moment Awareness)
Embrace the Perspective of God (Self-as-Context)
Embrace your Identity in Christ (Defusion)
Embrace the Mind of Christ (Values)
Embrace the Christ Life (Committed Action)
The six processes of ACT work together to build psychological flexibility, and research suggests that increased flexibility is a key mechanism through which ACT improves mental health and well-being (Hayes, Luoma, et al., 2006; Hayes, Villatte, et al., 2011; Stockton et al., 2019). Over the years, I have observed something similar in the people I've worked with: when they genuinely embrace these seven spiritual processes, they often report a greater sense of peace, steadiness, and well-being. What is most interesting is that most of my clients inform me that they are aware of these doctrines and believe them to varying degrees, but the gap was in actually living in light of those doctrines. Explaining these processes in a practical manner has helped many of them experience both spiritual growth and a greater sense of well-being.
If living the six processes of ACT builds psychological flexibility and supports mental and emotional health, consider what I have seen when people embrace these seven spiritual processes: their lives become increasingly marked by love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (Galatians 5:22–23, ESV). Did you catch that? Those are characteristics produced in us through the indwelling Holy Spirit, not by our own effort. Embracing these processes is not what produces that fruit; it is how we yield to the One who does. That is the heart of what I call the He Must Increase Model, drawn from John the Baptist’s words in John 3:30: “He must increase, but I must decrease.” The more we are yielded to Him, the more those characteristics become evident. Therefore, could we say that a life lived yielded to the Holy Spirit might have a positive effect on our mental and emotional health, while recognizing that some struggles also have biological or medical components that call for professional care?
