These verses of scripture that I read today give the idea the sacrament bread is a testament that we will remember Jesus. The water is a testament that we will keep his commandments. 
I realize that the bread and water of the sacrament are parts of an inseparable whole and are not something we can compartmentalize, but I love the idea for ways to help me focus my thoughts during the sacrament. Maybe I could use that time to think more carefully about how I can “remember and obey” during the week, when “ordinary life” kicks in. 

I think it could be tricky to do this if I had little kids, but I think you could incorporate it into a sacrament picture book for kids to look at during the sacrament to help them focus. Hmm, this may be a future gift idea!

3 Nephi 18 

7 And this shall ye do in remembrance of my body, which I have shown unto you. And it shall be a testimony unto the Father that ye do always remember me. And if ye do always remember me ye shall have my Spirit to be with you. 8 And it came to pass that when he said these words, he commanded his disciples that they should take of the wine of the cup and drink of it, and that they should also give unto the multitude that they might drink of it. 9 And it came to pass that they did so, and did drink of it and were filled; and they gave unto the multitude, and they did drink, and they were filled. 10 And when the disciples had done this, Jesus said unto them: Blessed are ye for this thing which ye have done, for this is fulfilling my commandments, and this doth witness unto the Father that ye are willing to do that which I have commanded you.
