Take the helmet of salvation...
Some of the most effective schemes of the devil and his evil forces are to convince us that God is angry at us, and is not loving, merciful, or kind toward us.
Another effective scheme is to convince us we can or have lost our salvation.
In Ephesians 1-2, Paul explains the nature of our salvation. Under the inspiration of the Spirit of Christ, Paul says that while we were dead in our sins, following the ways of the world, we became the objects of God's great love, abundant mercy, and bountiful grace that he kindly poured out upon is through Jesus for our sins.
