Premarital sex is considered immoral as its consequences leads to other immoral behavior and also breaking of the law. When people engage in unprotected premarital sex, it will lead to unwanted pregnancies and children born out of wedlock. This leads to mental and emotional stress for couples who are not ready to bear the responsibility of having children.
As premarital sex often occurs throughout teenage years and among teenagers and adolescents, many are not ready for unwanted pregnancies after engaging in premarital sex as they are neither mature nor responsible enough. This causes a number of unwanted pregnancies to be aborted Girls that do not abort their babies might abandon their babies as soon as they are born as they are unable to raise them. This leads to a rise in the number of babies being abandoned in the country.
Most of the time, these babies are often dead by the time they are found. Most importantly, as those that engage in sex before marriage usually have unprotected sex, there is a high risk for them to contract sexually transmitted diseases like Herpes, Chlamydia, Genital Warts, Gonorrhea, Acquired immune deficiency syndrome (AIDS) and other diseases as people who engage in premarital sex tend to have multiple sex partners. Some sexually transmitted diseases can be treated if early treatment is sought. However, there has been no cure from AIDS.
And it can totally destroy a young person’s life. Yes, sex is pleasurable, but in God's view, the primary purpose of sex is not recreation, but rather re-creation.

Rather, God commands against premarital sex in order to protect unmarried people from unwanted pregnancies, from children born to parents who do not want them, and to protect children from parents who are not prepared for them.
Imagine, for a moment, a world without premarital sex. There would be no sexually-transmitted diseases, there would be no un-wed mothers, there would be no unwanted pregnancies, there would be no abortions, etc. According to the Bible, abstinence is God's only policy when it comes to premarital sex. Abstinence saves lives, protects babies, gives sexual relations the proper value, and most importantly abstinence honors God
