-Note: This article has Jesus dying at age 40 (or slightly younger). The authors’ seem very confident that the crucifixtion of Jesus occurred in 33 CE. I can accept this date but have questions about Jesus’ birthdate. A recent recalculation of Herod’s death to 1 BCE would place Jesus’ birth at 2-3 BCE with His final physical age of death at about 35.

The age at which Jesus chose to sacrifice Himself to God (only for our transgressions) is at half lifetime (If we recognize, with Moses, that human life usually terminates at 70 years of age-Ps. 90.10). Thirty five years of age is the ‘prime of life’ and at which a person is usually at their height of power (function, cognizance). For His church-Jesus gave His life that we may experience His.
