How do we know God is immortal and invisible?

God's immortality and invisibility are core aspects of His divine nature. 1 Timothy 1:17 states, 'God…is immortal, invisible.' Immortality indicates that God exists beyond time and death; He is eternal and will never perish. Additionally, His invisibility reflects His holiness and purity, making Him beyond human comprehension. Light, for example, cannot be seen directly but is known through its effects. Much like light, God is known through His creation and actions, but His essence remains unseeable in its full glory. This mystery of God's nature invites believers to trust in His character rather than seek to fully understand Him with human intellect.
