The elect in the Bible are the Jews and not the Church.
When Paul speaks of the elect he is speaking of the Jews and not the Church. This is very important to be aware of especially when studying prophesy.
II Timothy 2:10 Therefore I endure all things for the elect’s sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.
Paul is talking about enduring many hardships for the sake of the Jews. If he had been talking about the Church well they already had salvation.
Clearly God's elect are the Jews.
