In the Old testament, God dealt directly with His people. In person, through objects (burning bush, cloud, fire, angels, ark),priests, and prophets. God dealt with people in Jesus' time through Jesus. He deals with people now through: holy spirit, Word, church, circumstances, and answering prayers. The church age was ushered in through Jesus Christ. We are that time where God is about to come back and get us. No one knows the time or the season. When He comes back, then He will deal with the Jews again, He's not done with them yet. There will be 144,000 sealed Jews. How are they sealed? The same way we are, through the blood of Christ. This all begins for gentiles in Acts 10.
