Holy Bible Online 
A grateful heart should be part of what it is to be a Christian. Anyone who recognizes that they have been saved through the sacrifice of Jesus Christ knows that they have done nothing to deserve this reward, they have received it only through the grace of God. Remembering this truth should make us grateful every moment of every day.
We didn't deserve anything, but through Jesus we have everything! Every day is a good day to say "Thank you, God, thank you, Jesus!"
