Mortality is the time to learn first of God and the gospel and to perform the ordinances. After our feet are set on the path to eternal life we can amass more knowledge of the secular things...Secular knowledge, as important as it is, can never save a soul nor open the celestial kingdom nor create a world nor make a man a god, but it can be most helpful to that man who, placing first things first, has found the way to eternal life and who can now bring into play all knowledge to be his tool and servant.
