The answer
Because the Lord of heaven wishes to make the heart of His church burn with the desire to depart to Him to enjoy the heavenly life.
God is present in His church (Cf. Rev. 2-3), heals her weakness, comforts her, and grants her the eternal heavenly joy together with the heavenly hosts.
It reveals how the heavenly hosts care for the church and support her that she may experience the sweetness of heaven.
The book of Revelation proclaims ‘Jerusalem’ the exalted heavenly city, being the “dwelling place of God with men”, and our eternal home.
Our knowledge of the heavenly hosts reveals to us certain aspects that apply to our current life of faith. In getting to know them, we learn more about their divine gifts and we desire to acquire these same features through God’s grace. Our study of the heavenly hosts in Scripture, the church’s Tradition, and the writings of the Church Fathers reveals to us hidden mysteries concerning the heavenly life, the holy church, and the spiritual life of the believer, especially servants.
