What does it mean that we were once in darkness before coming to faith?

In the sermon, it is emphasized that before encountering Christ, individuals sit in darkness, representing their moral and spiritual state of sin and separation from God (Matthew 4:16). Ephesians 2:1-3 explains that we were dead in trespasses and sins, living under the shadow of death. This state is contrasted by the light that Christ brings, which enlightens the hearts of believers, showing them their need for salvation. The transformation from darkness to light reflects not only a change in understanding but also a complete change in existence as one is called into the fullness of life found in Christ (Colossians 1:13).
