Family , friends , and Worthy leaders: are those who obey the Commands of Righteousness ( a relevant Biblical reference)
A certain Christian Theology refers that since Sentient beings were made in Likeness/ Similitude of an "IMMORTAL Spirit", they were designed towards "Existence/ continued Life" (& not towards death& it's allied manifestations of murder, suicide, euthanasia and neglect).
It also refers that to be Virtuous in efforts is to be Akin and Family with a 'Righteous ETERNAL Immortal Spirit Being' , & thus there is Continuance
for such ( Continuance is not dependant upon having children or kith kin)
