What does the Bible say about aging and service to God?

Scripture illustrates that aging is not a hindrance to serving God but rather an opportunity for deeper engagement in His work. Paul, referred to as 'Paul the aged' in Philemon 1:9, exemplifies this lifelong commitment to the service of Christ. Believers are encouraged to remain active in ministry, no matter their age, as they wield the armor of God and continue to fight the good fight of faith. The absence of retirement for a Christian signifies the endless calling to lead lives of worship and service until the Lord calls them home.
