This is deep.
I love your analysis of our heavenly reward as compared to our earthly rewards.
we need to be conscious of how we maintain our heavenly account.
Things of this world will pass away and we wont have any reward thereof, but there is a place where we can keep our treasure that can be secure and not be destroy by anything, that place is heaven.
We need to keep funding our heavenly account through our good deed and our walk with God and working for God while using our substance to promote and expand the kingdom.
Our priority should be seeking the kingdom of God and it's righteousness.
