Let's make sure we define faith as believing in the Lord, where such belief is not merely academic (such as that possessed by the devils, who believe and tremble), but belief as in love and heartfelt admiration and respect for that wonderful Person (the Lord) and all His unique attributes.

Although faith alone justifies, faith as the virtue you describe provides no assurance of salvation. Neither does agape love. The devil counterfeits both.

What Satan can not counterfeit is the promise of the gospel. We know our sins are forgiven, not on account of a virtuous faith or agape love, but because God has promised the forgiveness of sins to them that believe.

Martin Chemnitz, Loci Theologici,When faith does not err in its object, but lays hold on that true object, although with a weak faith, or at least tries and wants to lay hold on Christ, then there is true faith, and it justifies. The reason for this is demonstrated in those lovely statements in Philippians 3:12: “I apprehend, or rather I am apprehended by Christ” and Galatians 4:9: “You have known God, or rather have been known by God.” Scripture shows a beautiful example of this in Mark 9:24: “I believe; help my unbelief.”
