You say our preoccupation, indeed our raison d'tre for living/loving, must be grounded in our unworthiness as bearers of Original Sin. 

You tell us our lives on earth should be based upon and evaluated upon our assiduous avoidance of  "comfort and ease." You sound like a cult leader of those "it must hurt so good" sects. 

You make earth and our time here sound like a trial, a crucible, an exam, a vale of tears, a basic training exercise, and--deductively--a quest for "discomfort" and "uneasiness." 

Where in your paradigm do the following fit: unbridled joy, laughter, ecstasy, letting the good times roll, celebration, parties, more good times rolling, achievement, and letting go? 

You  present a scenario where our UNworthiness topples our worthiness as daughters and sons of God. To me, that's an insult to the One who--unlike you--says we are worthy of His love.  

You say kids of our Lord come to bat with two strikes (more?) against us. 

What a cruel  image of God as parent.
