The Lord Jesus said:

“. . . Yes — and if you embrace this kingdom life and don’t doubt God, you’ll not only do minor feats like I did to the fig tree, but also triumph over huge obstacles. . . . . Absolutely everything ranging from small to large, as you make it a part of your believing prayer, gets included as you lay hold of God.” Matthew 21:21-22 (MSG) 

“If you believe, you will receive whatever you ask for in prayer .” Matthew 21:22 (NLT) 

Therefore, I say: 

“I believe I receive the finish work of healing and health in my body by the finished work of Christ Jesus.”

(and/or)

“I believe I receive the finished work of abundance and supply in my life by the finished work of Christ Jesus.”
