>>Have I taken the mark?
A finger print could not be the mark of the beast. It is just a print or a impression of your finger.
Even if a person had taken the mark of the beast they have to worship the beast to perish. If it took just the mark, a parent could put the mark on a baby. But a baby can not worship a beast.
Rev. 14:11 And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast AND his image, AND whoever receives the mark of his name."
Matthew 4:10 Then Jesus said to him, "Away with you, Satan! For it is written, 'You shall worship the Lord your God, and Him only you shall serve.' "
God is a jealous God, you can not worship Him and worship at another alter also. For example, you can not worship God and worship at the alter of Nike (sports), Hilarities (laughter), or Aphrodite (goddess of love). So just the same, you can not worship God and the beast also.
