Instructed more perfectly

Doctrine and Covenants 88:77-80

77 And I give unto you a commandment that you shall teach one another the doctrine of the kingdom.

78 Teach ye diligently and my grace shall attend you, that you may be instructed more perfectly in theory, in principle, in doctrine, in the law of the gospel, in all things that pertain unto the kingdom of God, that are expedient for you to understand;

79 Of things both in heaven and in the earth, and under the earth; things which have been, things which are, things which must shortly come to pass; things which are at home, things which are abroad; the wars and the perplexities of the nations, and the judgments which are on the land; and a knowledge also of countries and of kingdoms–

80 That ye may be prepared in all things when I shall send you again to magnify the calling whereunto I have called you, and the mission with which I have commissioned you. https://www.lds.org/scriptures/dc-testament/dc/88?lang=eng
