English to Latin Translation of "Love is Strength"

English to Latin Translation

I would like to know how to say "Love is Strength" (in the sense that "love gives one strength" or that "from love, one derives strength") in Latin. I understand Latin has many variants on English words, so let me be precise. By "love" I mean in a romantic sense or that of a true friendship, and by "strength" I mean in the sense of an inner strength akin to confidence.

This is also for a tattoo.

Thanks
