When you are called to give, you will rationalize to give or not to give.

You might say, 'the economy is bad', 'my circumstances are not good', 'the time is not right', 'I gave a lot in the past', etc, and you might pass this time.

Alternatively, you will rationalize: 'I am healthy, enjoy peace, breathe fresh air, have support from my family, am blessed. Therefore I must give something.'

You can rationalize either way and justify your actions. I hope you will rationalize to give instead of not to give.
