In His divine essence, God cannot die; He is immortal. But because the God the Son assumed humanity, He is capable of suffering and death as a part of His atoning work. He assumed the likeness of sinful flesh in order to condemn sin in His own body through death (Rom 8:3–4). He was legally reckoned to be a sinner, though He himself was without sin, so that He might pay the penalty for sin (2 Cor 5:21) (Luke Stamps).
