Luke 6:35 But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
Matthew 5:21 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
Jesus teachings focus more on the intention of the heart.
Matthew 5:22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
How much more if you kill anyone?
Mateo 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
How about the suicide bombers who kill people in disguise of a holy war?
Matthew 11:13 For all the prophets and the law prophesied until John.
John the baptist is the prophet who baptized Jesus in Jordan river.
Luke 16:16 The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.
What holy war are they talking about?
Hebrews 8:8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Hebrews 8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away
For suicide bombers, I would say, you are all sons of the devil.
John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
The new covenant is not to kill your enemy but love your enemy as you love yourself.
