Commentaries:
God does care how we worship Him; He gives specific commands about how He wants to be glorified according to His standards and not our own. It does matter whether or not we share in the celebration of this world's pagan religious holidays. Though the Bible—the Word of God—makes no direct references to New Year's Eve, Lent, Easter, Halloween, or Christmas, the origins of these pagan holidays are mentioned as being abominations to God.
