Which takes us back to Romans 5. By Adam, death came into the world and only by Christ did the resurrection occur or overcoming death. Thus, Christ overcame both spiritual and physical death. Physical death was overcome by the resurrection of Christ for all. Spiritual death is overcome by Christ for those who take the opportunity to repent.
Rom 5:18 Therefore as by the offence of one [judgment came] upon all men to condemnation; even so by the righteousness of one [the free gift came] upon all men unto justification of life. (All will overcome physical death via the resurrection of Christ).
Rom 5:19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous. (Because of Christ we have the opportunity to overcome spiritual death by repenting of our sins and turning over our will to him.)
