Why did the agent at the gate in DIA said that we missed our flight?

We almost missed our flight from Denver to Atlanta...

After the Delta agent issued a new ticket and boarding pass for Christina, we only had 20 minutes before the plane departs at 11:05am. In 20 minutes, we had to go through the security checkpoint, take the train to gate C and walk to the gate. We arrived at the gate with only 6 minutes left before the plane takes off. The agent welcomed us with, "you missed your flight" at the gate. Since we did not board at least 10 minutes before departure, we lost our seats. There were two other people after us. The agent said, "take any open seat." There were only 5 seats remaining.

This was our second test of faith. With only 20 minutes before the plane departs, it is impossible to go through the security checkpoint, take the train and walk to the gate. God made it possible! Thank you for your prayers!
