Absolutely correct. Any single verse, taken by itself, does not prove anything at all concerning anything.
Reminds me of a pastors story. People would sometimes randomly pick a verse by closing their eyes, opening the bible and pointing at a line and assuming that the verse their finger landed on was the message from God for that day.
A despondent man did this and hit the verse, "Judas went out and hanged himself."
This shook him up so he tried again and hit, "Go thou and do likewise."
Now thoroughly rattled he tried once more and hit, "Do what you must and quickly."
No he didn't go commit suicide, he realized the folly of taking any verse out of context.
