Joseph F. Smith on Agency

As man now is, God once was; as God now is, man may be.

The Lord created you and me for the purpose of becoming Gods like himself.

These are the mysteries of the Kingdom of God upon the earth, to know how to purify and sanctify our affections, the earth upon which we stand, the air we breathe, the water we drink, the houses in which we dwell and the cities which we build, that when strangers come into our country they may feel a hallowed influence and acknowledge a power to which they are strangers.

Jesus had not finished his work when his body was slain, neither did he finish it after his resurrection from the dead; although he had accomplished the purpose for which he then came to the earth, he had not fulfilled all his work. And when will he? Not until he has redeemed and saved every son and daughter of our father Adam that have been or ever will be born upon this earth to the end of time, except the sons of perdition.
