What does it mean that Jesus has immortality?

In 1 Timothy 6:16, it is stated that Jesus 'only hath immortality,' which means He is the origin of eternal life and possesses an unending existence devoid of decay or death. His resurrection from the dead confirms this truth, demonstrating that He has conquered death, thus providing assurance to believers that they, too, will experience resurrection and immortality through Him. Importantly, any immortality experienced by humanity is derived from Christ; as He proclaimed, 'because I live, you shall live also' (John 14:19). This reflects the profound theological implication that outside of Christ, there is no true life, emphasizing His role as the source of life and eternity.
