Someone who's godlike is so wonderful, beautiful, or good that they resemble a god. To very young children, many adults seem godlike simply because they are large and powerful.
A devout religious figure might seem godlike to many of his followers — in other words, he seems more like a god than a fallible, mortal human being. The qualities of such a person, or those of a magical or mystical character, are also godlike: "Her godlike ability to become invisible came in handy when she was fighting the bad guys." The word comes from the Old English godlic, or "divine."
