As you can tell in the design, this does not say anything about Jesus, God, or even a bible verse, this was made intentionally for others to approach you and ask you, what do the Romans numbers in your sweatshirt mean? 

Here is where your mission starts, they are initiating a conversation, and by explaining to this person that these Roman numbers are actually a bible verse and explain to them what it means for your and how God saved you, this will help you be more confident to preach the gospel and influence in others!
