For the Lord will not cast off his people, neither will he forsake his inheritance (comp. Deuteronomy 4:31; 1 Samuel 12:22; 1 Kings 6:13; Isaiah 41:17). However long God's chastisements continue (see Psalms 94:3), the faithful may be sure that God has not forsaken, and never will forsake, them, since "he forsaketh not his saints, but they are preserved forever" (Psalms 37:28).
The promise is made equally to the faithful individuals ("his saints") and to faithful Churches ("his people," "his inheritance").
