Looking for tattoo that has the meaning "Goodness of God"

Can someone help me find tattoo symbols or letters that mean "Goodness of God" that is the meaning of my sons name Tobias and that is what I want to get a tattoo of!

Why not just get his real name?

Because if you know that is what hes name means, then why make it complicated? Its the same as this. You are a good person and do good deeds, then you decide to get a alter ego that means doing good deeds. If you know what I mean? Getting just his name makes it even more "powerful"
