The repetition of 8 in this Angel Number, combined with the number 4, is a revelation that the Archangels are involved in your financial affairs. You have made prayers for assistance with money matters, and now those prayers are being answered.
The reason you are going to experience abundance is that the Angels have taken note of your responsibility when it comes to money. You are quick to help others and generous.
Retain these qualities in your life and the Angels will continue to bless you.
