Lucifer walked away from his creator, and so did Adam and so can we if we're not careful and this is why the Bible is full of warnings and imperatives, from Genesis to Revelation. To sinners and Saints alike. If you walk away from Jesus you walk away from your savior and if you walk away from your savior you walk away from your salvation and if you walk away from your salvation you will lose your salvation, easy peasy, Grace and salvation is a gift with strings attached, God's love is unconditional but Salvation is conditional based upon believing and continually believing since the word believing many times is in the present tense. Easy peasy.
