Meet Our Speakers

Paul Tripp
Dr. Paul David Tripp is a pastor, speaker, and best-selling author. His driving passion is to connect the transforming power of Jesus Christ to everyday life. He lives in Philadelphia with his wife, Luella, of 50 years, and they have four adult children.
Paul will be presenting the following talks at Oxygen 2023:

Zack Eswine
A pastor at Riverside Church in Missouri, Zack describes himself as a ‘flawed but earnest’ encourager of those working in ministry. He is extremely passionate about supporting Christian ministry workers as they ask questions and speak honestly about their doubts and uncertainties. This passion has led to the founding of Sage Christianity: an organisation where Zack, along with wife Jessica, aim to create a safe space for those in ministry to bring their doubts into conversation with the wisdom of Jesus.
When he’s not busy mentoring, preaching or writing a book, Zack enjoys watching ‘old’ movies, reading a good novel or essay, and cheering on his basketball team with his four kids. When he really needs to focus on Jesus, Zack likes to sit by the ocean; he says that it calms his mind and helps him zero-in on God’s voice.
Zack will be presenting four talks at Oxygen 2023 on:
1. Wisdom Practices for a Minister’s Life (Ps. 111:10)
2. Practicing the Beginnings of Wisdom for your own life (Ps. 34:11; 86:11)
3. Practicing the Consolations of Wisdom for the people you serve (Ps. 25:12, 14)
4. Practicing the Global Breadth of Wisdom for the generation you inhabit (Ps. 33:8)

Seeking to blend personal ministry experience with the latest psychological research and practice, Grant now focuses on the well-being and development of Power to Change missionaries as well as providing psychological services for other Christian organisations and clergy/missionaries.
Grant’s workshop:
Serving Confidently Amidst Strain, Uncertainty and Change
Living through the past few years has introduced the reality of living and ministering in an environment of uncertainty and change that our generation has not seen.
For some, change and uncertainty can be experienced as initially stimulating – a challenge to embrace. But even if that was an initial response, living in an environment of chronic change and uncertainty can leave us feeling uncertain, deeply fatigued, and even incompetent in areas we previously felt competent.
This workshop will build your capacity to cope with change and help you serve Jesus amidst uncertainty. Grant will present a framework for understanding why change generates fatigue and stress, explore work and spiritual resources that can promote a greater sense of motivation in an environment of change, and personal practices that enable us to persevere with vigour.
