There is a story about a rather legalistic Seminary student who wanted to have a scriptural basis for everything he did. He felt he was on solid ground if he could quote the Bible, book, chapter and verse to okay his actions.
He did all right with that until he began to fall in love with a beautiful co-ed. He wanted very much to kiss her, but he just couldn’t find a scripture to okay it. So, true to his conscience, he would simply walk her to the dormitory each night, look at her longingly, and then say "Good night."
This went on for several weeks, and all the time he was searching the Bible, trying to find some scripture to okay kissing her good night. But he couldn’t find one, until finally he came across that passage in Romans that says, "Greet each other with a holy kiss." He thought, "At last, I have scriptural authority for kissing her good night."
But to be sure, he went to his hermeneutics professor to check it out. After talking with the professor, he realized that the passage dealt more with a church setting than with a dating situation. So once again he simply didn’t have a passage of scripture to okay kissing his girl good night.
That evening he walked her to the dormitory and once again started to bid her "good night." But as he did, she grabbed him, pulled him toward her, and planted a ten-second kiss right on his lips.
At the end of the kiss, the Seminary student gasped for air, and stammered, "Bible verse, Bible verse." The girl grabbed him a second time, and just before kissing him again, said, "Do unto others as you would have them do unto you."
