But the possible costs of an unexpected pregnancy, abortion, and sexually transmitted disease as well as the deep hurts that can come from a broken relationship outweigh the feelings of the moment. All good things are worth waiting for. Waiting until marriage to have sex is a mature decision to control your desires. There are two ways to respond to this question. One is to explain why contraception goes against God's plan for sex, even in marriage.
Sex is for deepening love between a husband and wife and for the procreation of children.
God intended for these two purposes to be inseparable. This is an awesome and sacred privilege being able to cooperate with God in the creation of his own children, whom he desires to live eternally in his company. Contraception is contrary to God's plan because it artificially separates sexual love from its God-given power to create new life. No matter what type of contraception is used, a girl can still get pregnant. It happens and then there is a developing life to deal with.
