Proverbs 25:14 Whoever falsely boasts of giving is like clouds and wind without rain.
If you want to go down the route of boasting about all the good things that you do when you have not actually done them, you are following in the footsteps of the evil one.
If you promise all manner of great or good things and never actually deliver on those things, then you are doing exactly what Satan does to us every day.
Just as Satan tempted Christ in the wilderness, we too will be tempted to follow his lies and deception. Look at them as being those clouds that never bring rain… useless and empty!
