“He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things” (Romans 8:32)?
On the subject of God’s love and the impossibility of anything separating us from that love, Paul’s argument is from the greater to the lesser. If God has accomplished for us the greatest good conceivable, the giving over of his own son, then will not all other blessings naturally follow? Since God has made the ultimate sacrifice, why would he not bring to fruition in the end everything he originally intended? His ROI (Return On Investment) is guaranteed.
