We're being remade into something new. But what's the engine driving this change, and what's the ultimate goal? It has everything to do with knowledge and God's own image.
The verse reveals two crucial aspects of this 'new self':
Renewal Through Knowledge
The 'new self' isn't just different; it's actively being 'renewed in knowledge.' This isn't just accumulating facts; it's a deep, intimate 'knowing' of God, as Barnes points out. It's about understanding truth, particularly divine truth, which counteracts ignorance and deceit. This knowledge transforms our perspective and aligns our thinking with God's reality.
Becoming Like the Creator
The purpose of this renewal in knowledge is to reflect the 'image of its creator.' As Meyer and Calvin explain, this points back to the original state of humanity, created in God's likeness. This image wasn't just about intellect but the whole person – our reason, will, righteousness, and holiness. While the fall marred this image, the new self is being restored to that original, perfect reflection of God's character. It's about becoming more like Christ, who is the perfect image of God.
