… give up their OWN earthly lives for Christ – they do NOT take the life of another!!!
(Matt 10:39; Ex 20:13)
… DO ONLY GOOD – to all, equally, whether we think they deserve it or not.
(Matt 5:45 )
… observe the Sabbath day as a day of rest and re-dedication to God.
… embrace suffering and endure through it to the end – as did Jesus with the cross.
(The above is by no means an exhaustive list, but could be a good start, taking also note of Motes and Beams.)
