Muslims might argue that if Jesus is the true light, then God the Father must be a false light, which contradicts the nature of God.

The New Testament presents Jesus as the true light that illuminates creation, as seen in John 1:1-10, where He is described as the source of life and light for all humanity. The term 'true' (alethinos) indicates that Jesus embodies the reality of light in a way that is genuine and not counterfeit. Furthermore, Jesus explicitly claims to be the light of the world in several passages (John 8:12, John 9:4-5, John 12:35-36). This raises a question about the nature of God the Father, who is also described as light in 1 John 1:5. The apparent contradiction can be resolved by understanding that the Father’s light is not false but rather is a reflection of the true light that is Christ. Therefore, the Father’s light can be seen as derived from Christ, who is the ultimate source of all illumination and truth. This interpretation does not diminish the Father’s divinity but rather highlights the unique relationship within the Trinity, where the Father, Son, and Holy Spirit coexist in perfect unity and truth.
