How does "open wide" relate to sin?
What does "open your mouth wide" reveal about the nature of sin?

The Text in Focus

“I am the LORD your God, who brought you up out of the land of Egypt. Open your mouth wide, and I will fill it.” (Psalm 81:10)


What Does “Open Your Mouth Wide” Mean?

• Picture a fledgling bird, beak stretched in full trust that the parent will supply.

• God invites Israel to the same posture—absolute dependence and eager expectation.

• The command is literal: receive what He gives. The promise is literal: “I will fill it.” There is no hint of scarcity in God.


How the Phrase Exposes the Nature of Sin

• Sin resists the posture of need.

– Refusal to “open” shows pride (Psalm 10:4).

• Sin doubts God’s generosity.

– Israel preferred idols, believing God withheld good (Psalm 78:18-19).

• Sin seeks satisfaction elsewhere.

– They “filled themselves” with wilderness cravings, not with God (Numbers 11:4-6).

• Sin shrinks the capacity for blessing.

– A closed mouth cannot be filled; unbelief limits experience of God’s abundance (Mark 6:5-6).

• Sin forgets redemption history.

– He reminds them of the Exodus; rejecting His filling ignores past deliverance (Deuteronomy 8:11-14).


Supporting Passages

Jeremiah 2:13—“For My people have committed two evils: They have forsaken Me, the fountain of living water, to dig their own cisterns…”

Isaiah 55:1-2—“Why spend money on that which is not bread?”

John 6:35—“I am the bread of life. Whoever comes to Me will never hunger.”

James 1:14-15—Desire, when conceived, gives birth to sin; sin promises fullness but ends in death.


Practical Takeaways

• Keep the mouth wide: cultivate continual, humble dependence.

• Expect God’s abundance, not meager rations; sin whispers that God is stingy.

• Identify competing fillers—idols, habits, ambitions—that crowd out His provision.

• Remember past deliverances; gratitude fuels open-mouthed faith.
