LOVE is God's will... Anything outside of love is not of God, therefore He cannot reward, or pay, you for it. It's not a threat, it's just a simple fact. God does not reward evil, and anything outside of God's will is 'evil'.
The one you work for is the one you'll receive payment from.
The LORD rewarded me according to my righteousness;
According to the cleanness of my hands He has recompensed me.
Death and curse is not a threat... Life and blessings are simply God paying His workers for a job well done. :)
But if serving the LORD seems undesirable to you,
then choose for yourselves this day whom you will serve...
But as for me and my household, we will serve the LORD.”
