One at a time and I will do this all day for you to understand. But make your questions clear so I can clearly answer them!
I Peter 5:13
"The church that is at Babylon, elected together with you, saluteth you; and so doth Marcus my son."
Who is Peter talking to so we know who the "elect" are here?
I Peter 1:1-2
"Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia,
Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
Peter is speaking to Gentiles, they are the "elect" through faith in Christ.
The Gentiles are not the "elect" called by God in His original calling to introduce Christ to the world.
The Church must realize we are God's second choice. That is very significant to the Word of God.
