The goal of every Christian is to become like God or joined with God. The essence of that would be to become sinless. For God to give us powers is nothing. To wash away sins and forgive was/is the difficult part. With God anything is possible.
Not all the church fathers’ attempts at improving theology hit the mark. This one doesn’t, and there is a good reason it is not in the bible.
We can and must become godLY. Filled with God, changed from our old evil way of living to one that shows the characteristics of God inasmuch as they can be expressed through a human vessel. That doesn’t make us God. And I’m glad it doesn’t because I wouldn’t want that impossible task, impossible because of all the omni’s involved.
Going to heaven in a Christian sense means getting heaven in us too. It’s mutual.
Our life is hidden with Christ in God, but we do not become God, contrary to what the Catholic church does teach in its catechism.
And just in case someone wants to know where......

460 The Word became flesh to make us "partakers of the divine nature":78 "For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God."79 "For the Son of God became man so that we might become God."80 "The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods."81
