Amen

The Hebrew triconsonantal root of the word amen has the following meanings:

  • To be firm
  • Confirmed
  • Reliable
  • Faithful
  • Have faith
  • Believe

So when you say, “amen”, you are believing by faith and simultaneously affirming and confirming it to be true.
Or, put another way, it’s like saying, “I believe! Yes, I believe!”
