Hi APAK, yes, I agree with all that you stated. But, do be careful, marks is trying to prove God's love prior to creation. All the points that you made, in regard to God exuding His love, were true but occurred post creation. marks is claiming that in order for God to be innately and eternally capable of love, it necessitates the existence an object for His affection, from eternity. Thus, marks has concluded that there must've been an eternal son within the Godhead, in order to satisfy this requirement.
I personally cannot see what type of loving and meaningful dynamic can take place between two persons that know everything, can do everything, and are everywhere simultaneously, and are entirely complete and self-existent in and of themselves?
What does one omniscient person say to another omniscient person, 'how are you?' or 'what are you up to?', or 'should we create something today?'.
Each one knows everything before it is even said, and has the answers to everything without any need to consult anyone, and has the power to do everything on their own.
What extreme and utter nonsense!
