How do we know God is immortal and uncorruptible?

The immutability and immortality of God are essential traits of His divine nature. In 1 Timothy 1:17, Paul reveals God as 'immortal' and 'uncorruptible,' which means He cannot decay, die, or be subject to the limitations of time and space. This is crucial because it assures believers of God's unchanging faithfulness and His ability to accomplish His eternal purposes without fail. When we realize that He is eternal and cannot be influenced by external decay, we grasp the depth of His covenantal promises to His people.
