Why We Are Sometimes Called Away?

"Many are still tested as Abraham. They do not hear the voice of God speaking directly from the heavens, but He calls them by the teaching of His word and the events of His providence. They may be required to abandon a career that promises wealth and honor, to leave congenial and profitable associations, and separate from kindred, to enter upon what appears to be only a path of self-denial, hardship, and sacrifice. God has a work for them to do; but a life of ease and influence of friends and kindred would hinder the development of the very traits essential for its accomplishment. He calls them away from human influences and aid, and leads them to feel the need of His help, and to depend upon Him alone, that He may reveal Himself to them." PP 126-127
