That's a gross distortion of Mormon theology.
First, Smith is not considered to be a god, any more than any of the prophets of the Old Testament are considered to be gods by the Jewish or Catholic community.
Second, the doctrine that man is destined for godhood doesn't mean in this life, or very soon into the next. Do you believe in eternal life? Where do you see yourself in ten million more years? A hundred? If life is eternal, then it's a valid question, isn't it?
how can you become a god when jesus said God is your father: And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth.
You just answered your own question. God is your father. What child doesn't want to grow up to be like his father?
Problem is you want to jump the Creator-creation gap which totally diminishes God's total "I AM" position.
Mormons like so many religions can't accept that God is not them nor are they able to become Him. Never the less like most religions, it's humanistic origins feed into the comfort zone and safety of fallible humanity by offering godhood after death.....I.E. a type of immortality that is so off-base.
Jesus said He has prepared a place for all believers, but never did He say that "You too, can become just like Me". Try and find that in both the old and new testament?
He is the Shepherd and we are the sheep. That is if we are His, and that involves salvation, and Jesus laid that out pretty clearly. "You must be born from above Nicodemus".
Also Mormons have such difficulty with just believing without the input of feelings, emotions, dreams, burning bosom experiences to re-inforce their belief system. Instead the God says that faith comes from believing on His Word(Holy Scripture), which does not involve the eyes, dreams, smell.......etc...
Phillip met the Ethiopan Eunoch who was a very high rank in his country. The gentleman was actually reading OT scripture on his way back to his native country from Jerusalem. Phillip noticed and asked the Ethiopian if He undeerstood what he was reading? The Ethiopian did not, and Phillip proceeded to show him how the OT foretold of the Messiah/Christ/Savior from no doubt Isaiah, Micah, Amos, Jeremiah, and many other OT books. The Ethiopian "Believed!", and was baptized. Phillip went on his way as God led, and the Ethiopian went home rejoicing in His new found faith and salvation.
It is the Word of God that transforms.......whether it was Jesus in person speaking or the scriptures working with the Holy Spirit that Jesus sent in His stead.
*******
Mormons don't realize that the enemy, Satan, is alive and well and keeps this world in perpetual detours from finding salvation, as he/Satan works on the ego, and Adamic/lost souls hopelessness with tantalizing little and big carrots to lead folks away from the Gospel.
There is absolutely know way to be sure that a vision or dream or urging is of God without going to the scriptures and seeing if it is in agreement.
Satan does not project himself as evil, but as a beautiful light and way for all. He is the gread deceiver, and he has authored most of the religions of the world.
