Not Your Own
"Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies."
Although the section that these verses come from speaks directly to immorality, there is an even greater context to it: we are not our own, but were purchased at a greatest price, the sacrifice of Christ as he laid down his life to atone for the sins of all mankind. This design, inspired by retro styling from 1970s concert posters, utilizes eye catching colors to pop off the black shirt to proudly exclaim that we happily accept the fact that we are not ours.
The verse, in English and Korean (but customizable for your group's needs), comes from 1 Corinthians 6:19-20.
