I think I have stumbled upon (been Spirit inspired about) something that needs to permanently change my way of thinking.
Thankfulness comes from a true recognition of grace and favour
Favour once given should still bring thankfulness even though that favour may no longer be available. If you can't appreciate what was given then you are not really viewing it as favour but as a right. If you feel you've lost that right, you will not be thankful, appreciative or happy. If you view it as favour even if it is removed, you remain thankful for it cause you recognise it was favour not a right.
Celebrate favour given. If you steward favour well, more is given.
We need to be on guard against an entitlement mentality. If I asses favour as a right that is owed me then I feel I have an entitlement. This is not a kingdom way; I am owed nothing in fact, I owe everything but because of grace, because of favour. I am debt free. Therefore any perceived loss is a loss of something I had no right to; as it was favour given.
As an example,when I was a Priority Privilege member, I gained certain privileges or favour as a result of that membership. What is interesting is that I expected those privileges and when they weren't available I felt annoyed and unthankful. In a spiritual sense the viewing of favour as a right will cause the spirit of entitlement to kick in and I become unthankful for something that was a privilege or favour not a right.
Personal application:
Whilst in church I heard someone behind me singing. Unfortunately they could not hold a note and it was difficult to listen to. My immediate thinking went to the enjoyment and pleasure that I used to gain from being able to sing and I began to become despondent because that is something that I have now lost, due to the stroke.

It suddenly dawned on me that instead of being thankful for the favour that was given to me for many years I began to enter into a spirit of entitlement whereby I viewed the ability to sing as I right that was mine and therefore the loss of that caused a lack of appreciation and thankfulness. Ultimately unless this view is recalibrated, this will lead to anger, bitterness and depression.

Alternatively, if I view the fact that I was able to sing for many years as 'favour' then the loss of that favour, although difficult, should still produce a spirit of thankfulness As it was something that I didn't deserve, nor did I earn ( it was not a right), but it was favour given and as a result, thankfulness should ensue.this applies to so many areas in my life.
Okay,for me to share this is quite difficult as it exposes some of my inner struggles. But I do so with the hope that not only will this give 'food for thought' for others, but will also hold me accountable to others so that if I fall into the trap of feeling sorry for myself again and become unthankful, then by virtue of the fact that I have shared this, I am opening myself up to accountability.
