When you are in an airport, notice the difference between passengers who hold confirmed tickets and those who are on standby. One reads the newspaper, chats with their friends or sleeps, while the other hangs around the ticket counter, pacing anxiously. What is the difference? Confidence!

If you knew that in 15 minutes you must stand before God, what would your reaction be? Would you pace or say to yourself, ‘I cannot wait?’ Paul writes: ‘The Spirit himself testifies with our spirit that we are God’s children’ (Rom. 8:16). In other words, the Spirit whispers, ‘Relax, you have trusted Christ, you are on the flight to heaven.’ Beloved, check yourself: are you sure you are on the flight?
