Ephesians 4:17-24

Put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.

Pastor Mark discusses the concept of transformation in the Christian life, emphasizing the need for both subtraction (putting away former ways of futile thinking and actions) and addition (embracing new thinking and living in righteousness and holiness). His personal anecdote about renovating his kitchen illustrates the comprehensive nature of this transformation. The sermon further delves into the challenges of changing old patterns and the importance of a renewed identity in Christ, explaining how true change starts with a change in thinking and relies on Christ for both the subtraction of old ways and the addition of new, righteous living.
