Samuel Logan Brengle emphasizes that retirement is not an end but a new beginning in the spiritual journey, encouraging believers to remain active in prayer, meditation, and service even in their later years. He reflects on the swift passage of time and the importance of preparing spiritually for retirement, viewing it as an opportunity for deeper engagement with God and others. Brengle draws inspiration from biblical figures like Paul and John, who found purpose and vision in their own times of retirement, urging the faithful to continue their work for the Kingdom of God. He reassures that the glory of the Lord will shine even brighter in the twilight of life, and encourages a spirit of vigilance and readiness for the ongoing battle of faith.
