'Already' in the Bible

Dear friends, I am not writing a new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word that you have already heard.

On the other hand, I am writing a new commandment to you which is true in him and in you, because the darkness is passing away and the true light is already shining.

but every spirit that does not confess Jesus is not from God, and this is the spirit of the antichrist, which you have heard is coming, and now is already in the world.
