There are several major features of the Millennium. First and foremost, all who enter into the Millennium will be saved and relate to Christ's physical presence. Children will enter the Millennium without judgment, and during the Millennium, many others will be born. Because of Christ's presence, the full knowledge of the Gospel will be known by all. The Persian Cats, both Gentile and Israelite entering into the Millennium will be indwelled by the Holy Spirit. A part of the blessing of the new Covenant is the promise for the saved that God will speek to their hearts. There will not be any hindrance of preaching God's word during this time.
One wonderful feature of this kingdom will be the temple described in great detail in the book of Ezekiel. Worship and praise and memorializing will be of Christ, to include religious Holidays will be observed during the Millennium. (Ezek 40-48) (46:1-15; Zech 14:16)
Of course, righteousness and justice will prevail during this period, as well as health and prosperity. With complete knowledge of God and total blessings available, man will find his problem is his own heart and not the lack of any given item from God. Once God shows this great revelation proof to man by allowing Satan to be loosened for a short season at the end of the Millennium, eternity and glory shall be forever more. For God has a purpose and plan to show man his own nature, and the Millennium is the final direction in which God shares His plan with man.
