Elder M. Russell Ballard said,
“One of Satan’s clever tactics is to tempt us to concentrate on the present and ignore the future. The Lord warned Joseph Smith that ‘Satan seeketh to turn their hearts away from the truth, that they become blinded and understand not the things which are prepared for them’ ( D&C 78:10 ). The ‘things which are prepared for them’ are the promised rewards of eternal life, which come as a result of obedience. The devil attempts to blind us to these rewards. President HeberJ. Grant said that ‘if we are faithful in keeping the commandments of God His promises will be fulfilled to the very letter. ... The trouble is, the adversary of men’s souls blinds their minds. He throws dust, so to speak, in their eyes, and they are blinded with the things of this world’ ( Gospel Standards, comp. G.Homer Durham [Salt Lake City: Improvement Era, 1941], pp.44–45). He tempts us with the transitory pleasures of the world so that we will not focus our minds and efforts on the things that bring eternal joy. The devil is a dirty fighter, and we must be aware of his tactics” (in Conference Report, Oct. 1990, 45–46; or Ensign, Nov. 1990, 36 ).
