What are the features of the Church of the New Covenant after the ascension of Christ?

Since Christ, the Head of the Church, ascended to heaven, the Church enjoyed what the Lord promised His disciples, “the kingdom of God is within you” (Luke 17:21) and the main task of the Church became to draw the hearts and minds of the believers to the heavenly throne of God by the grace of the Holy Spirit, where the Head of the Church is seated at the right hand of the Father.
