The Protocol That Never Quits

Every time you send a text message or load a webpage, something remarkable happens beneath the surface. The internet runs on a protocol called TCP — Transmission Control Protocol — first designed in 1974 by Vint Cerf and Bob Kahn. What makes it extraordinary is this: it was built to never give up.

When data travels across the internet, it breaks into small packets. Some get lost along the way — dropped by overloaded routers, corrupted by interference, swallowed by congestion. TCP notices every missing piece. And it resends. If the second attempt fails, it waits a moment and tries again. And again. Each retry waits a little longer — what engineers call "exponential backoff" — but TCP never stops trying until the message gets through.

You and I are living by a similar protocol. Paul wrote, "Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up" (Galatians 6:9). Some of our prayers feel like lost packets. Some acts of faithfulness seem to vanish into the void. But the call of the gospel is to keep transmitting — to keep loving, keep serving, keep believing — even when we cannot yet see confirmation that our signal has been received.

The God who invented persistence wove it into the very architecture of how the world communicates. He wove it into you, too.
