Could you put the slogan on the outside with blue lettering and position each section like on a clock: "Share the Gospel" from 9-12 o'clock reading clockwise, "Wear the Gospel" from 12-3 o'clock reading clockwise, "Share the Gospel" from 7-5 o'clock reading counter clockwise. Positions are approximate.... try to make it look balanced. There should be a thin circle band around the slogan.
Also send a couple color schemes of the shirt maybe oraganes, yellows.
