This sermon, drawn from Psalm 71, presents a profound meditation on the nature of faith in advanced age, portraying it not as diminished but as deeply resilient and active. Centered on the psalmist's cries for divine faithfulness amid physical decline and spiritual assault, the message highlights the persistent challenges of doubt, weakness, and the fear of final defeat, yet counters them with unwavering assurance in God's constant presence, availability, and power. The preacher emphasizes that true faith in later years is marked by persevering hope, persistent praise, practical godliness, and bold public testimony, all grounded in God's unchanging character and the gospel's righteousness. Far from being a message only for the elderly, it is a call to all believers to sustain their trust in God's promises regardless of age or circumstance, affirming that faith, sustained by grace, overcomes every trial and leads to final vindication.
