His purpose was that He would build up and establish only these as His mount Zion (31:4-6) and remnant people (31:7). He would only become a Father to those who willingly separated from Babylon, which was made up of all the religious nations--including God's once chosen church.
Kanyang layunin na kanyang itayo at itatag tanging ang mga ito bilang kanyang bundok ng Sion (31:4-6) at nalabing bayan (31:7) Siya’y magigigng Ama lamang doon sa handang humiwalay sa Babilonia, na binubuo ng lahat ng relihiyosong bansa-kasama na ang dating piniling iglesia ng Dios.
