Marks of a Christian - Thomas Bell

"These are the three decisive marks of being in the covenant of grace: conviction of sin, faith in Christ, and holiness of life. By the first we see our misery, by the second we accept of deliverance, and by the third we testify our thankfulness to him who delivered us. The first has a relation to the covenant of works, the second to the covenant of grace, and the third to the law of Christ."

Thomas Bell, A Treatise on the Covenants of Works and Grace. p. 183
