The rapid changes in our culture often leave Christians feeling confused and vulnerable. We need to raise up disciples of all ages who can think biblically about the issues of our time so that they can serve God faithfully and share the gospel confidently. We need to get beneath the surface of how people live and speak to understand how behaviour reflects ultimate beliefs that are either true or false. This seminar will explore the centrality of transformed thinking to whole-life discipleship. It will present a biblical worldview that challenges alternative ideas and provides a foundation for confident faith and persuasive evangelism. We will explore together both what this means for individual Christians and how, in practical terms, teaching in our churches can develop disciples who engage thoughtfully in the world.
