Acts 27:17 & Psalm 91: God's protection?
How does Acts 27:17 connect with God's protection in Psalm 91?

A ship in crisis, a people under cover

Acts 27:17

“After hoisting it up, they used supports to undergird the ship. And fearing that they would run aground on the sandbars of Syrtis, they lowered the sea anchor and were driven along.”

Psalm 91:3-4

“For He will deliver you from the snare of the fowler and from the deadly pestilence. He will cover you with His feathers; under His wings you will find refuge; His faithfulness is a shield and rampart.”


Acts 27:17—Human effort meets divine oversight

• The sailors “used supports to undergird the ship”—they wrapped ropes or cables under the hull to hold it together.

• They “lowered the sea anchor” to slow the drift.

• Their skills mattered, yet the chapter repeatedly shows God steering events (Acts 27:23-24, 34). Human action and God’s protection operate side by side, never in competition.


Psalm 91—The unseen shield

• “He will deliver… He will cover… His faithfulness is a shield.”

• The psalmist pictures God Himself reinforcing, surrounding, and anchoring the believer.

• Notice the same two-fold dynamic: believers act (“dwells… abides,” v. 1), yet safety rests on God’s initiative (“I will protect him,” v. 14).


Point of connection: undergirded versus covered

1. Undergirding a hull

– Physical ropes hold planks together.

– The ship is kept from breaking apart.

2. Being covered under wings

– Spiritual refuge holds the heart together.

– The believer is kept from coming apart.

Both images stress support from beneath and shelter from above—comprehensive protection.


Shared language of protection in Scripture

• “Shield and rampart” (Psalm 91:4) matches “supports to undergird” (Acts 27:17) in function, if not vocabulary.

Psalm 46:1 — “God is our refuge and strength, an ever-present help in trouble.”

Isaiah 43:2 — “When you pass through the waters, I will be with you; and the rivers will not overwhelm you.”

2 Corinthians 1:10 — “He has delivered us… He will deliver us again.”


Living the connection today

• Tie down what you can (wise choices, practical steps), just as the sailors did.

• Trust God to hold what you cannot—He is the rope beneath and the wing above.

• Expect His presence in every storm; Psalm 91 is not mere poetry but a promise proved on Paul’s deck.


Key take-aways

• God’s protection is both structural and surrounding.

• Human responsibility never negates divine sovereignty; it responds to it.

• The same Lord who kept Paul’s ship intact keeps every believer secure—His “faithfulness is a shield and rampart.”

What precautions did the sailors take, and how can we apply this today?
