Why does the Bible contain...

• James 2:17
  Thus also faith by itself, if it does not have works, is dead
   
• James 2:24
  You see then that a man is justified by works, and not by faith only
   
• James 2:26
  For as the body without the spirit is dead, so faith without works is dead also
   
• Matthew 7:21
  Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven
   
• Mark 16:15-16
  Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned
   
• Revelation 22:14
  Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city
