This doctrine is clearly taught in these passages, John 10:28,29 ; Romans 11:29 ; Philippians 1:6 ; 1 Peter 1:5 . It, moreover, follows from a consideration of (1) the immutability of the divine decrees (Jeremiah 31:3 ; Matthew 24:22-24 ; Acts 13:48 ; Romans 8:30 ); (2) the provisions of the covenant of grace (Jeremiah 32:40 ; John 10:29 ; 17:2-6 ); (3) the atonement and intercession of Christ (Isaiah 53:6,11 ; Matthew 20:28 ; 1 Peter 2:24 ; John 11:42 ; 17:11,15,20 ; Romans 8:34 ); and (4) the indwelling of the Holy Ghost (John 14:16 ; 2 co 1:21,22 ; 5:5 ; Ephesians 1:14 ; 1 John 3:9 ).

This doctrine is not inconsistent with the truth that the believer may nevertheless fall into grievous sin, and continue therein for some time. (See BACKSLIDE .)
