Sure we can. "You shall not murder." (Ex. 20:13), (Matt. 5:21) and (Romans 13:9). Any action that causes murder of an innocent human life is wrong. Most artificial means of contraception on the market today (pills, IUDs, implants) have as a back up mechanism the prevention of a fertilized egg from implanting - which is, in essence, abortion. For many years, this fact was left out of instructions and information given to women. Hopefully, this is not now still the case. We also have from Scripture instructions concerning sexual acts restricted to a married man and woman only. So, I believe we have more than ample Scripture to guide us. God has not left us without His word of truth and we do not need to solely rely upon fallible men to tell us what is right and wrong.
