No Spirit, No Teaching

D&C 42:14

For I know without the Spirit I cannot teach. Everytime I give a lesson I ask for Heavenly Father's help in providing the Spirit so my lesson may be edifying. John Bytheway said in one of his books that I read, is that the missionary doesn't but it is by the Holy Ghost that man shall be taught. The missionary can invite the Holy Ghost, but without it there is nothing to be felt and the investigator doesn't feel anything. If it's playing the piano for sacrament or giving a lesson in Elder's quorum I always ask for the Spirit to be with me.
