Gratitude is recognizing the bonus value for favorable things or positive life experiences for which we did not actively work towards or ask for.
Everyday you are blessed. You are recipient of things that are good and not so good, but all that you receive requires a response to the Father. Your response to the Father, invites future blessings into your life. A simple Thank-you Father, is all it takes to honor Him for all the goodness and mercy He has shown you. It is showing appreciation for what we may not have asked for, may not deserve, and /or did not pray about.
Thanksgiving is not the only time to show appreciation. It is proper to give thanks everyday. Each day we are blessed with life, an earthly home, air and water. The essentials of life. Then God see's fit to give you so much more.
A Father rewards His children who are gracious, grateful and good.
