The elect are NOT the sons of disobedience.
The word "
elect" can be used to refer to the already saved saints in whom God chooses based on His foreknowledge.
1 "Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia,
2
Elect according to the foreknowledge of God the Father,"
(1 Peter 1:1-2).
Meaning, God knows who is going to accept Him, and as a result they are the "elect."
However, the word "
election" can refer to being a chosen nation, but that does not mean that nation is saved or living in God's will, kind of like Israel.
"As concerning the gospel,
they are enemies for your sakes: but as touching the
election,
they are beloved for the fathers' sakes." (Romans 11:28).
This above verse is talking about Israel. The nation of Israel is a part of the election of God. They are a chosen nation, but they were not always doing God's will, and they rejected their Messiah. Granted, in the end times, they will be driven to the wall to repent and accept Jesus as their Messiah, but that has not happened yet. Again, God knows that in the end, Israel will be a saved nation. So they are a part of the "election" of God.
Judas was a chosen disciple but that does not mean He remained in that office. The Scriptures say he fell by his transgression. He betrayed the Lord. Yet, he was one of the chosen disciples of God.
We are to make our own calling and election as being sure.
"Wherefore the rather, brethren, give diligence to
make your calling and election sure: for if ye do these things, ye shall never fall:"
(2 Peter 1:10).
We are told to put on certain qualities as identifying of the Elect of God.
"
Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering;" (Colossians 3:12).
Our fate is not chosen already. We can either be like the Elect of God, or we can be like a son of disobedience. The choice is ours to be as the elect of God if we cooperate with the Lord and His plan of salvation for our life. We can make our calling and election sure by doing the things that Peter suggests.
For God desires to have all men to be saved (1 Timothy 2:3-4); For God is the Saviour of all men, specially of those that believe (See: 1 Timothy 4:10).
Many are called, but few are chosen.
We are chosen by God by our own actions towards Him.
God chooses us ahead of time because He knows what we are going to do long before we were born.
