This song is excellent...
We need to remember:
We are rebels against God, literally sinners, living with us at the centre of the universe
God knows this but sent his son Jesus to die for that sin so we don't have to pay the price
He does this becasue he loves us
He then allows us to receive this great truth, not because we do anything that earns it but just because!
Jesus did it all, does it all and will do it all - by grace!
This song helps us see it again a fresh.
