They are born again in Christ.
God, however, has the foreknowledge to know who will choose to believe him though that person does not yet exist.
God foreknew that Jeremiah would believe Him and thus could sanctify and ordain him before hand
In that sense, God foresanctified and foreordained him
God likewise foreknew us
Agree.
God, Who knows the end from the beginning (Isa 46:9, 10), predestined us - descendants of Adam & Eve - to adoption as sons in Christ (Eph 1:4-6). Hence, we all are born in Him, instead of born in sin. This truth was emphasized by our Lord Himself in the parables of the lost sheep, lost coin, and lost son. see Luke 15:1-24.
1. Before the sheep got lost, it was in the sheepfold under the care of its shepherd.
2. Before the coin was lost, it was with its owner.
3. Before the son went lost, he was at home with his father.
So with us all. We start out in life NOT lost. And to be NOT lost is to be in Christ. But we all sinned, and like sheep went astray (Isa 53:6). Hence the command to repent (Luke 13:3, 5).
Repentance is the Greek "metanoia" - change of mind for that which is good. Confronted with the opportunity and about to do evil, one changes his mind and does good instead. IOW, it is overcoming evil with good.
The command to repent is the same command God made in the old testament (Ezek 18:30); the same command God now wants all men to obey (Acts 17:30); the same command Jesus made in the gospel that He preached (Mark 1:14, 15); the same gospel He wanted preached to the world before He comes again (Matt 24:14).
But alas the brand of gospel being preached to the world is tainted with an impurity - the doctrine that people are born in sin, instead of born in Christ. That somehow explains why Christ has not yet returned: the gospel He wanted preached before He comes again is NOT being preached to the world. Preachers need to remove that impurity and in its stead tell people that they are born in Christ. Being in Christ, the ONLY Source of power for doing good, they are part of His Body and are therefore heaven-bound, UNLESS & UNTIL Christ Himself blots one's name out from the book of life for not overcoming evil with good (Exo 32:32,33; Rev 3:5). And there's hope while alive for judgement is rendered only when a person dies (Heb 9:27).
Hence, while alive, we all are enjoined to overcome evil with good (Rom 12:21). Overcomers will Christ NOT blot out from the book of life (Rev 3:5) and will be seated with Him on His throne even as He Himself also overcame and sat down with the Father on His throne (Rev 3:21).
When Christ comes again to reward every man according to what each has done (Matt 16:27; Rev 22:12), all NOT blotted out from the book of life will be allowed entry to the heavenly portals (Rev 21:27); all blotted out will have their portion in the lake of fire (Rev 20:15).
The apostle Paul has cautioned of a curse for preaching a gospel other than the gospel of Christ (Gal 1:6-9). Are you ready & willing to remove the impurity from the gospel that you preach?
