Trusting God's timing in impossible promises?
How can we trust God's timing when promises seem impossible, like in Genesis 17:17?

Setting the Scene: Genesis 17:17

“Then Abraham fell facedown. He laughed and said to himself, ‘Can a child be born to a man who is a hundred years old? Can Sarah give birth at the age of ninety?’”


Observing Abraham’s Reaction

• Abraham’s laughter sprang from sheer amazement, not rebellion.

• His honest question highlighted the gap between human limits and divine ability.

• God did not rebuke the laughter; He reaffirmed the promise, underscoring that His word is unshakeable (Genesis 17:19).


Recognizing God’s Immutable Character

• Faithful: “God is not a man, that He should lie… Has He spoken, and will He not fulfill?” (Numbers 23:19)

• Sovereign: He rules over the impossible (Luke 1:37).

• Eternal: Time constrains creation, never the Creator (Psalm 90:4).

• Purposeful: “So My word that proceeds from My mouth will not return to Me empty” (Isaiah 55:11).


Lessons on Waiting for Fulfillment

• Age, circumstance, and human weakness cannot thwart God’s plan.

• Delays refine faith; they are not divine disinterest.

• God’s timeline magnifies His glory—no one could credit Isaac’s birth to natural means.

• Fulfilled promises often become the seedbed of future covenant blessings (Romans 4:19-21).


Practical Steps to Rest in God’s Timing

1. Rehearse His promises aloud from Scripture.

2. Surrender personal deadlines; align desires with His revealed will.

3. Obey in present assignments—Abraham continued circumcision and hospitality while waiting.

4. Cultivate gratitude for past faithfulness; yesterday’s deliverances fuel today’s trust.

5. Surround yourself with believers who speak life and truth (Hebrews 10:24-25).


Blessed Outcomes of Trusting His Schedule

• A deeper, tested faith that honors God (1 Peter 1:7).

• A testimony that strengthens others facing impossibilities.

• Joy that surpasses circumstance, anchored in divine certainty (Psalm 40:1-3).

• Participation in God’s redemptive storyline, far larger than personal comfort.
