"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" (I Corinthians 3:13).

"These things have I spoken unto you, that my joy might remain in you, and that your joy might be full" (John 15:11).

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

There are many things in life we can well do without, but there are at least seven things a Christian simply cannot do without. These are outlined in the following listing.

"An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas: For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth" (Matthew 12:39-40).

"How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, purge your conscience from dead works to serve the living God?" (Hebrews 9:14).
