The Bible does not give us two key pieces of data to answer Paul's age at death: when he was born and when he died. Therefore, an exact age cannot be given. However, we can estimate that he likely died in his 50s or 60s. This is based on the following:
Paul was described as a young man when Stephen was stoned (Acts 7:58). That event likely happened between 33 and 35 AD. The Greek word translated as “young man” has been understood to denote individuals aged from their late teens to their 40s. It is probably that he was in his early 30s. If true, his birth is estimated to have occurred between 1 and 5 AD.
Calculating the date of his death is equally uncertain. However, 2 Timothy’s language of imminency suggests it was written just before his death (2 Timothy 4:6–8). Before that letter, Paul referred to himself as an “old man” (Philemon 9). While “old man” is also subjective, given life expectancies, 50s-60s sounds reasonable. That estimate is supported by early church tradition, which placed his death during Nero’s persecution (64–68 AD). Regardless of his age, Paul lived faithfully for God until He called him home.
Paul was a man just like us. Certainly, God used him mightily, but we should be careful not to raise him to a pedestal. Paul, himself, noted that he was still a sinful man (Romans 7:18) who needed to strive to bring his flesh into obedience (1 Corinthians 9:27) and even had crushing struggles (2 Corinthians 1:8–9). However, through it all, he modeled a life that places Jesus above all other things (Philippians 3:8).
While we don’t know when Paul died, the New Testament gives us his life as an example to follow. We must learn to place Christ first in our life (Philippians 1:21). We must continue to look forward to His return (2 Timothy 4:8). We must be content in our circumstances (Philippians 4:11). We must desire that others would be saved (Romans 10:1). We must love other believers (Romans 12:10). We must encourage one another (1 Thessalonians 5:11). We must place the well-being of other believers over ourselves (Philippians 2:3–4). We must long that God would be glorified in everything we do (1 Corinthians 10:31). Like Paul said, we should be imitators of those who follow God faithfully, like Paul, just as they seek to imitate or reflect Christ (1 Corinthians 11:1).
