1:10 What teaching underlies what Peter says here?
The underlying teaching here is that Christians cannot take their faith and salvation for granted. Believers must ensure their salvation by developing the Christian graces Peter enumerated in V5-7 (CP V5-7).
If these graces are not evident in a Christian's life it is because he or she has deliberately failed to develop them (CP V9).
In the Greek construction of this verse the word "forgotten" here points to a deliberate act. It suggests that the believer, by failing to make the effort to grow in grace as instructed in V5, has in effect wilfully turned his or her back on the stand they made for Christ when they were saved.
This implies the possibility of apostatising - reverting to their old way of life (CP 2:20-22)
The phrases, "...giving all diligence" in 1:5, and "give diligence" in 1:10, demonstrate that believers must be actively involved in their spiritual growth (CP Mt 12:30; Jn 6:27; 1 Cor 9:24-27; 15:58; 2 Cor 7:1; Ga 6:7-9; Eph 4:1; Php 2:12-13; Col 3:1-17; He 6:10-11; 12:1-2; 2 Pe 1:10-11; 3:18).
Believers who pursue the qualities listed in 2 Pe 1:5-7 will never fall into sin and fail God's grace.
