Serious Reason, and attitude.
NFP (words, accronym) should not be used. This is a labeling of the liberal ways. What we truly have is God's Design, anatomy physiology since Adam and Eve. Why this long to see the beauty of God's design is questioinable.
Federal grants got a hold of God's Design and made it rotten. So, when taught, there is no mention of God in any way. Planed Parenthood called it High tech Rhythm when condoms are added. When PP teaches condoms, it is right over the cervical mucus and creates pregnancy to abortion to the person going to contraception and abortion pills. Come to find out New Order teaches the same way only saying condoms maybe needed by a married couple. What lies. Whether it be AIDS or such, condoms do no salvation.
Dr. Billings stated, and I was there to hear him, "This is not yours! This is God's!" He was furious, because attitude was rotten of those taking federal dollars. I was offered to sign papers to the affect and I refused knowing the enemies.
We will be judged of our heart, attitude. We regret that there may come a time to postpone or such, but the object of God's design it not mortal sin, sin is of the person, soul that makes sin occur, from the heart. So, I agree with the use of God's design when in serious reason.
