After you have asked and as you are accepting, you should make thanksgiving a constant piece of your request. Thanksgiving comes when you put your circumstance in God’s grasp, and you pass on the result to Him. The explanation you can express appreciation is on the grounds that you realize God has heard your request and you trust that He will do what is best for you in that. For this you can express gratefulness. Give thanks to receiving your miracles. That’s it!!!
