How does God divide light from darkness in the believer's life?

In the life of a believer, God performs a work of separation between light and darkness, symbolizing the new creation they are in Christ. As seen in Genesis 1:4, God divided the light from the darkness, which serves as a metaphor for the transformative work of regeneration. Christians, now children of light (1 Thessalonians 5:5), experience a moral and spiritual renewal where the old self, associated with darkness and sin, is contrasted with the new self, which embodies righteousness and truth. This division is significant, as it helps believers to recognize their new identity in Christ and the continued struggle against sin in their lives.
