God did not direct his children to help him eternally save souls. His commandment to his preachers and teachers is to inform his children as to how he wants them to live their lives while they are on earth. God has the power to accomplish all of his will, by himself, in eternally saving all that he wants to. Man has no righteousness of his own, only the imputed righteousness of Christ. John 17:2, As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
