In the Gospels, sometimes words do not always mean what they seem to mean. Here are a few examples: God remembered Rachel...She conceived and bore a son. "Remember" sometimes means "to do a favor for someone" or "to intervene on behalf of," as in Genesis 30:22-23, quoted above. Are we to assume that God forgot Rachel and then suddenly remembered her? Certainly not!
In Genesis 40:14 Joseph requested the chief butler to "remember" him when he was restored to his position in Pharaoh’s court. Yet the butler did not "remember" Joseph, but "forgot" him as stated in verse 23. Should we assume that Joseph only desired the chief butler to think of him from time to time once the chief butler was reinstated? No, Joseph was requesting the chief butler to intercede on his behalf with Pharaoh.
In Luke 23:42 the thief on the cross requested of Jesus, "Remember me when you come into your kingdom." Jesus did not wait to grant the favor. His immediate response was, "Today you will be with me in paradise."
Yet the chief butler did not remember Joseph, but forgot him. "Forget" is another word which does not always mean what is seems to mean in English Bible translations. It can mean "not to intervene on behalf of," or "to abandon." As in Genesis 40:23, noted above, the chief butler "forgot" Joseph, or simply did nothing for him. In I Samuel 1:11, Hannah petitioned the Lord not to "forget," or abandon her, but to "remember" her; in other words, favor her with a son.

[Donna note: To "remember" always implies that some sort of action will be taken. This is interesting to think of in relationship to the Sacrament. When we covenant to "always remember Him" it means much more than a mental exercise. It means that our actions will always reflect the covenants we have made.]
