A martyr is one who is killed for his faith. Only two individuals are specifically named as martyrs in scripture: Stephen and Antipas.
Many who understand the wickedness involved in murder fail to realize that the scripture also warns “Whosoever hateth his brother is a murderer.”
At times, God called people to enter into war with the goal of killing their enemies. The Bible clearly distinguishes between this type of killing and murder.
Capital punishment is not confined to the Old Testament and is not done to the exclusion of God’s grace, but rather as an act of God’s just judgment.
