Follow the logic. Help me out if I am wrong.
Premise #1 - the following definition of love is an accurate one.
Love is choosing what is best for another despite the cost to yourself.
-My own definition cobbled together from several others.
Premise #2 - the following statement is true.
"Love your neighbor as yourself"
from Matt 22:39 / Mark 12:31 / Lev 19:18 / Gal 5:14 / James 2:8
Premise #3 - if we love as we defined love in #1 and we follow the command of #2, then we are supposed to choose what is best for ourselves, even if it costs us everything, including our lives.
Premise #4 - the "best choice" for ourselves is eternal beatitude, also known as heaven.
Premise #5 - if the best choice for ourselves is heaven and we are to love others as ourselves, then we should love others enough to choose what would help get them to heaven - even if it costs us everything, including relationships, our reputations, our possessions, or our lives.
Makes sense to me. If only it were easy.
