=Hope4More;12883626]In Leanna's faith, selfless love of God means trusting absolutely in God's will, accepting that everything is part of His plan, and submitting (emphasized) to His will.
Selfless love (in this context)also means trusting that Cooper is safe with God and existing in a state of perfect joy (he died an innocent, before he was considered responsible for sins, so is perfectly pure). To wish for him to return would be the ultimate act of selfishness, and an admission of a failure of faith, just when she most needed her faith to endure (she has said this).

Personally I don't think Leanna owes anyone an explanation about anything, much less about something so profoundly personal as to why she grieved the way she did over the sudden, preventable, horribly painful death of her only baby-- whether or not that grief conformed to the expectations of perfect strangers.
For anyone trying to understand why she said and did what she said and did, though, imo understanding her faith is a good place to start.
