'Remember' in the Bible

Remember what I told you: "A servant is not greater than his master.' If they persecuted me, they will also persecute you. If they kept my word, they will also keep yours.

But I've told you this, so that when the time comes you'll remember that I told you about them. I didn't tell you this in the beginning, because I was still with you."

When a woman is in labor she has pain, because her time has come. Yet when she has given birth to her child, she doesn't remember the agony anymore because of the joy of having brought a human being into the world.
