In that context, I think you mean 'As to security', not assurance.
Assurance is simply knowing you are indeed saved.
Assurance comes from seeing Christ in your behavior, your behavior being the outward evidence that Christ really is in you in salvation by the Holy Spirit.
Security, on the other hand, comes from believing in Christ.
Christ himself and his ministry in heaven being the secure thing about salvation.
