I agree with scripture, that the old testament saints are in the kingdom of Heaven, Jesus led captivity captive. The question raised was that you had to be born again to see the kingdom of God. When was Abraham, born before Jesus, born again? " And when He was demanded of the Pharisees, when the kingdom of God should come, He answered them and said, The kingdom of God COMETH NOT WITH OBSERVATION: Neither shall they say Lo here! or, Lo there! for , behold, the kingdom of God is within you." Luke 17:20-21. The kingdom of God is not a place, the kingdom of heaven is. The kingdom of God is where God rules and reigns in individuals, while in the kingdom of heave God rules the universe, " Matthew 11:12 " From the days of John the Baptist until now the kingdom of heaven suffers violence, and the violent take it by force." If the kingdom of God, who is love, can be taken from you and the bible says that " nothing, even violence, can separate us from the love of God " For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus." Romans 8:38-40. When the Spirit of Christ, and the Spirit of the Father indwells us, then the " kingdom of God " is within us, while the kingdom of Heaven is a physical place. As I said before, the old testament saints who believed in God's redemptive plan, if, like Abraham, they saw that day, or not, they were granted entrance into the kingdom of Heaven, after Jesus sprinkled His blood on the mercy seat.
