Peter shows us that the true grace of God is the full orbed salvation from election and regeneration to sanctification and suffering for Christ, and ultimately our future glory in Christ.
1 Peter 5:8-11
We are in a spiritual warfare. Peter, therefore, calls us to alertness and sobriety of mind, to be steadfast in our faith. He urges us with the danger at hand, portraying our enemy as a prowling and voracious lion. But God is in control. He will use every onslaught of the enemy to advance His purpose to sanctify and strengthen His people.
