Basic Manual for Priesthood Holders, Part A, pg. 77; “Our Need for General Authorities –

Throughout history Heavenly Father has revealed His will to men on the earth through His prophets. This is true whether we are talking about the time of Noah, Moses, or Joseph Smith. Conditions may change, but the truth does not. Because of our continuing need for God’s direction, He has given us a prophet and apostles and other General Authorities to guide us today.”

Romans 10:9; “That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.”

We are commanded to confess our sins, confess that Jesus is God and believe God raised Jesus from the dead.  We are encouraged to live our lives like we are saved being encouraged by other Christians (Heb. 10:24). It is only through Jesus and His word that we are guided today.  Conditions have changed only in the technological sense. And the condition of how we are saved was already changed when He spilled His precious, holy blood upon the Cross of Calvary.  We are still sinners and in need of Him only.
