The most dangerous silence is the one that tempts us to "help" God. During the 25-year gap, Abraham and Sarah got tired of waiting and produced Ishmael. We learn that what we do in haste (Ishmael) often persecutes what God does in promise (Isaac).
The Scenario
Abraham received the promise at 75. At 85, nothing. At 99, nothing. The silence was not God's absence, but the preparation of the stage so the miracle would be undeniable. God needed Abraham's human strength to die so divine power could be born.
The Investigation
In this interval, God changed his identity before changing his reality.
- Name Change: God changed his name from Abram ("exalted father") to Abraham ("father of multitudes") when he still had no legitimate children. He had to speak by faith before seeing by sight.
- The Laughter of Doubt vs. The Laughter of Grace: Sarah laughed in disbelief at the beginning of the gap, but laughed in joy at the end. The waiting time turned cynicism into celebration.
The Conclusion
Do not try to fabricate what God promised to generate. If the silence is long and biology says "no", you are on the perfect ground for a miracle. God is not late; He is meticulous.
