Cup
What do you like your cup filled with? It's what the cup contains that makes the cup significant. Jesus used the metaphor of a cup to speak about our lives and about suffering and blessing, but, most importantly, he used a cup to illustrate the new covenant relationship that we have with God.

Our lives are like a cup: God cares most about what's inside (our hearts).
