I want to be there now. Give it to me now. I know I don't deserve it. I know I can't pay you back for it. But I want it, and I will take it, and it will be mine forever.
Nothing hurts the giver more than the recipient trying to pay for the gift.
And yet we try to pay for it. If you love Me you'll keep my commandments. I want your love, and then the commandments will come and all the good deeds will come out of your love for me, but it won't get you to heaven. Just evidence that I live in your heart. Don't try to pay Me for heaven.
