Luke 21:16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death.
Why are they betrayed? Because they believe in Jesus as Lord.
Luke 21:17 And ye shall be hated of all men for my name's sake.
To be hated by all, is wonderful, if for the name of Jesus.
Mat 5:11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
Mat 5:12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
Luke 21:18 But there shall not an hair of your head perish.
Wait? "some of you shall they cause to be put to death?" Jesus speaks of eternal life in your new resurrected body -- with hair.
Luke 21:19 In your patience possess ye your souls.
Do not give up or despair, Jesus is Lord, your sorrow will be turned into eternal joy and your adversaries will be sorry, too late.
