satan knows this sequence

Parents can prevent a lot of heartache by teaching their children to postpone romantic relationships until the time comes when they are ready for marriage. Prematurely pairing off with a boyfriend or girlfriend is dangerous. Becoming a “couple” creates emotional intimacy, which too often leads to physical intimacy. Satan knows this sequence and uses it to his advantage. He will do whatever he can to keep young men from serving missions and to prevent temple marriages.
