"And almost all things are by the law purged with blood; and without shedding of blood is no remission." (Hebrews 9:22)

"But the Lord is faithful, who shall stablish you, and keep you from evil." (2 Thessalonians 3:3)

"Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is." (1 Corinthians 3:13)

"But wilt thou know, O vain man, that faith without works is dead?" (James 2:20)
