Hi Victoria. Thank you for commenting.
You write: "But all denominations and preachers within them interpret the bible differently. "
True, though there is more widespread agreement on some parts of the Bible as opposed to others.
"There is no set definition for what anything in it means...."
There is no set definition that everyone in the whole world mutually agrees upon. True.
"...so yeah, people will always look for what they want to see."
That is indeed human nature, but it's not what the Bible encourages.
"And so we have the prophetic word confirmed, which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; knowing this first, that no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit." (II Peter 1:19-21, NKJV)
