There is a bible verse from John 15:13 that says "Greater love has no man than this, that a man lay down his life for his friends." This was displayed everywhere. Military Aid Archibald Butt put others in the lifeboats and then stepped back not saving himself but the lives of others. Isador Strauss was given the opportunity to get into a lifeboat but refused saying "I am old and will not go before the younger men." John Jacob Astor the richest man on board was in a lifeboat and when it became full, he saw a 3rd class washerwoman and her child and he and his wife gave them their seats. 25 year old Edith Evans and her cousin Caroline Brown were told only one of them could board a lifeboat. Edith said she would stay telling her that she has a husband and children waiting at home and then walked off as the boat was being lowered.
There are so many tales of heroism and some have never been told. But you men must be willing to do such things as the Lord Jesus Christ did.
