Christian objections to palmistry usually come from the Bible's broader rejection of divination, sorcery, omens, and attempts to gain hidden knowledge through occult means. Palmistry is not always named directly, but fortune-telling is the neighborhood it usually gets placed in.
If palmistry is used to predict the future, reveal fate, choose relationships, or guide major decisions, most traditional Christian voices would say no. If it is used as light entertainment or personality talk, some Christians are less alarmed, though many still advise avoiding it because the line gets slippery rather quickly.
The blunt verdict: Christianity is generally much more comfortable with prayer, wisdom, counsel, and conscience than with someone staring at your hand and announcing that destiny has excellent penmanship.
