Dennis Patten "Pat" Duncan

From an early age, Pat learned the dignity of work, earning money to help with personal needs and home expenses—an early reflection of the steady devotion and perseverance that would shape his life. He served his country with courage and commitment, spending four years in the Air Force and four years in the reserve, carrying forward a faithful sense of duty and quiet strength.

In all he did, Pat was deeply cherished and beloved—known for a gentle, kind-hearted spirit, a patient way with others, and a generosity that asked for little in return. He could meet life with resilience and wisdom, and he offered compassion and thoughtfulness in ways that made people feel seen and valued. Even in serious moments, Pat’s warm humor could bring comfort, reminding those around him that steadiness and light can exist side by side.

Pat’s adventurous spirit was evident in the life he loved outdoors. He enjoyed hunting, fishing, and camping—simple, meaningful pursuits that suited his grounded nature and appreciation for time well spent. He was also a hard-working and devoted provider, owning and operating Pat's Mobile Glass for more than 25 years, a testament to his reliability, skill, and the pride he took in honest work.

Pat shared a remarkable life with his wife, Clara. Together they celebrated 60 years of marriage on January 7th, a milestone that spoke to enduring loyalty, selfless love, and a partnership built on steadfast care.

Isaiah 9:6-7 KJV

6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.

7 Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the Lord of hosts will perform this.

Romans 8:1-6 KJV

8 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.

2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.

3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:

4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.

5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.

6 For to be carnally minded is death; but to be spiritually minded is life and peace.

John 11:25-26 KJV

25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:

26 And whosoever liveth and believeth in me shall never die.

John 15:10-12 KJV

10 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.

11 These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.

12 This is my commandment, That ye love one another, as I have loved you.
