Being someone who has gone through the metamorphosis, called in Christianity the new birth, I see "god bless" and "good luck" as equals. Because my new birth required me to do what Isaiah 7:14-16 is believed to be what Jesus did, I have, as he did, forsaken the 2 kings over the abhorred land of death, god and devil, since verse 22 say everyone who survives the tribulation must do what Jesus did in verses 15 & 16.
Once reborn we begins as a child one has to grow into adulthood again like the tadpole, after its metamorphosis it still has to grow into frog adulthood, therefore, everyone who goes through the spiritual rebirthing has to do the same as the christ child and I am a 28 year adolescent after 36 years of being reborn.
Because of that awareness, I will say thank you to both while realizing everything any one does is their destiny, they do no good nor evil, they only follow their life's requirement the law or "reaping and sowing" or "karma" has them preforming. That is necessary because as Paul said, "the law is a school master," we are on earth to experience every attribute every life type on earth experiences before we are able to obtain the "dominion powers" (Genesis 1:26 & 28) Jesus demonstrated to qualify us to enter the "true" promise land.
