“Now Joshua was old and advanced in years when the Lord said to him, ‘You are old and advanced in years, and very much of the land remains to be possessed.’” Joshua 13:1
There is no set “retirement age” for the Christian, for there is always “very much land to be possessed.” Joshua had survived 40 years in the wilderness, then led in the long hard conquest of Canaan, and was now at least 80 years of age.
Not only was he “old and stricken in years,” but God even told him he was old! But instead of allowing him to settle down to enjoy a few retirement years in his hard-won new home, God sent Joshua out once again for further conquests.
That must always be the case with those who love and serve the Lord. There is still much Scripture to study and learn, many people yet to reach with a gospel witness, many with whom to share God’s love and comfort, much money yet to be earned to give to missions. Even those who must retire from active service or become confined at home still have much praying to accomplish.
No one who knows the redemptive love of Jesus Christ is ever too old to possess more “land” for the Lord. “The righteous man will flourish like the palm tree, he will grow like a cedar in Lebanon. Planted in the house of the Lord, they will flourish in the courts of our God. They will still yield fruit in old age; they shall be full of sap and very green” (Psalm 92:12-14).
Old age eventually comes to everyone who survives youth and middle age, but that does not mean it is time to quit. “O God, You have taught me from my youth, and I still declare Your wondrous deeds. And even when I am old and gray, O God, do not forsake me, until I declare Your strength to this generation, Your power to all who are to come” (Psalm 71:17-18).
