The word katabole often translated as "foundation" actually means overthrow. This refers to the downfall of the first creation age. The plan never even came into being until it became necessary at the overthrow. By then God wasn't loving very much - He destroyed the whole earth. It is because you do not understand the sequence of events between the original creation and the recreation of earth that you do not understand why Christ said, "For God so loved the world" - past tense. Since you seem to dispute the first creation age, I look forward to you addressing the scriptural evidence that I have provided to support it in this thread? See posts #491 #494 #496 Then we can discuss "foundation" more fully.
I do NOT dispute the first creation age at all. I absolutely believe it. God created it, it literally went to H*ll when Satan rebelled and was kicked out of His heavenly position. The earth reaped the complete destruction that Satan brought to it. God destroyed it and began again. But Before He began again, He had a plan for this man, Adam that He was going to create. “From the foundation of the world” and “Before the foundation of the world”. That was when the earth was RECREATED, not created.
