Do not open the door

Resistance Is Weakened by Opening the Door—Do not see how close you can walk upon the brink of a precipice and be safe. Avoid the first approach to danger. The soul’s interests cannot be trifled with. Your capital is your character. Cherish it as you would a golden treasure. Moral purity, self-respect, a strong power of resistance, must be firmly and constantly cherished. There should not be one departure from reserve; one act of familiarity, one indiscretion, may jeopardize the soul in opening the door to temptation, and the power of resistance becomes weakened. [15] – {AH 404.2}
Satan Would Eclipse the Future Glories—Satan has worked continually to eclipse the glories of the future world and to attract the whole attention to the things of this life. He has striven so to arrange matters that our thought, our anxiety, our labor might be so fully employed in temporal things that we should not see or realize the value of eternal realities. The world and its cares have too large a place, while Jesus and heavenly things have altogether too small a share in our thoughts and affections. We should conscientiously discharge all the duties of everyday life, but it is also essential that we should cultivate, above everything else, holy affection for our Lord Jesus Christ. [16] – {AH 404.3}
