What works for me is affirming prayers. I like to know that I am affirming to God and I’m asking for his will to be done. When I do this I never have to worry about the outcome.
Sometimes when I hear about people using affirmations they are worried about getting the wording right so that the Universe or Karma or whatever don’t give them any negative side effects for what they are asking. When I pray, I never have to worry about that because I ask for God’s will and the results are always God showing his favor.
