As many of my followers know I turn 90 this year. I hope that this post about Caleb will inspire older people that if you are walking with God obeying His commands, then age is not a barrier. God will empower you to do all that He gives you to do.

In our modern culture, age is often viewed as a season of withdrawal. We talk of “fading away” or “passing the baton”. However, the kingdom of God operates on a different timeline. In Scripture, later life is not a decline; it is a time of spiritual authority, clarity, and legacy.

From Moses beginning his primary calling at 80, to Anna the prophetess encountering the Messiah at 84, the pattern is consistent: calling does not retire. Perhaps the most striking example of this ‘senior strength’ is found in the life of Caleb.

At 40 years old, Caleb stood at the edge of the Promised Land. While ten other spies saw giants and fortified walls, Caleb saw opportunity, grounded in God’s faithfulness. His report was simple: “We are well able to overcome it” (Numbers 13:30).

But then came the delay. Because of the nation’s unbelief, Caleb spent the next 45 years wandering in the wilderness. He had been right, yet he had to wait. He had faith, yet he had to walk through the same dust and heat as the doubters.

What did Caleb do during those four decades? Numbers 32:12 provides the answer: he followed the Lord wholeheartedly. He did not allow the ‘wilderness years’ to embitter him, nor the delay to diminish his vision.

When he re-emerges in Joshua 14, he is 85 years old — and his spirit is unchanged. He famously declares: “Now give me this mountain” (Joshua 14:12). Caleb did not ask for a peaceful valley or an easy retirement. He asked for the hill country — the very place where the giants lived; the very giants the nation had feared 45 years earlier. His faith was resilient, unwavering and unmovable. He refused to let go of hope in God’s promise.

This remains our invitation today. Whether we are praying for revival in Australia, sharing the gospel with those God brings across our path, or waiting on a long-delayed promise, we are called to remain steady — to persevere.

Like Caleb, we may find ourselves in seasons of waiting where the reality around us does not yet appear to reflect the promise. Yet, through the blood of Yeshua, your past does not disqualify you, and God is not limited by your age. Your ‘later years’ can be your most impactful ones. The wilderness is not the end of the story; it is the training ground for the mountain.

The goal remains the same: to follow the Lord wholeheartedly, trusting that he who promised is faithful and he will do it (1 Thessalonians 5:24).
