Wives, Do NOT waste your time using sex as a bargaining tool. That is a lie from the enemy, it is manipulation and against scripture. It is NOT a tool that helps build your marriage in any way. However it is an act to destroy your marriage. Pleasing your mate, now that is how you use your time wisely. Now that's a good time spender.
1 Corinthians 7:4-6 (NLT) The wife gives authority over her body to her husband, and the husband gives authority over his body to his wife. Do not deprive each other of sexual relations, unless you both agree to refrain from sexual intimacy for a limited time so you can give yourselves more completely to prayer. Afterward, you should come together again so that Satan won’t be able to tempt you because of your lack of self-control. I say this as a concession, not as a command.
