A few interesting facts
"kingdom" is nearly always used of the physical kingdom(s) in the O.T.
scriptures. In the new testamnt, it occurs 137 times; 100 of
those times used by Christ. Kingdom of heaven, of God, kingdom,
It is almost always physical in the Old -- nearly always
spiritual in the New/
"Faather" is used twice in the Old in reference to God; 256 times
in the New !!!
"children of Israel " in the Old
"children of God" in the new.
Sonship is a NT concept as well.
God as a personal God is a NT concept -- different from the Old.
I am doing a study on the kingdom, for myself after Lance gave
encouragement for the study.
