God’s reminder that everything is a blessing from Him. It’s all part of His perfect plan. It’s all part of His sovereign plan for me. Or more maybe God doesn’t want you to go because you are not ready yet.
The best part is after say a year when you look back you realize how trivial that was and there are much more important things in the world to worry about.
So yes it happens and it’s a very terrible feeling. But God knows and He has planned this for you. So take God’s blessing graciously knowing God has only good intention for you!
