If we are the bride of Jesus, we will be one with him, then one with god.
As some have pointed out, one is always able to distinguish a wife from her husband, which means, in whatever sense they become one, it is not in the literal, physical sense where they take on one another's nature so that they are in every respect indistinguishable from one another. We don't take on God's divine nature such that we become God Himself, either. That is the old temptation of the devil in Eden: "You shall be like God..." Even if we could somehow become as God, we could never claim full equality with God, being created by Him and contingent upon Him. God has never been so, which is, in part, what makes Him God.
It's rather like the whole transgender business where a man tries to be as much like a woman as possible, even growing breasts, and altering his sexual organs, and consuming female hormones. No matter how much like a woman a man appears and behaves, his genes are always male. Even the most womanly transgendered man will never endure a monthly period, or undergo menopause, or become pregnant. Because, at his genetic core he is unchangeably a man, not a woman.
So, too, with us and God. No matter how much a human could appear to be God, like Him perfectly in respect to power, knowledge, presence and character, a human began to exist and he had a sin-nature at one point, and he was weak and ignorant, too. This has
never been true of God. Never; for if it were true, He would not truly be God. By definition, God exists as a necessity of His own being, uncaused, unchanging, always having been perfect in all His various attributes, which no human could ever claim, no matter how God-like s\he could become.
