Why would you tell people that are "elected" to repent? They are already assured of heaven. Repent means to turn from sin. You're eternally saved, what are you repenting for?
Spiritual Israel, not the nation of Israel, is made up of every kindred, and tongue, and people, and nation (Rev 5:9)
Spiritual Israel is representative of Jacob, of whom God changed his name to be no more called Jacob, but to be called Israel (Gen 32:28 & Rom 9:11).
God blinded the eyes of most of spiritual Israel, from understanding the gospel, until they repent, due to their turning away from him, and worshiping idols. These are the "wicked that he has no pleasure in their death=separation. They are referred to in the scriptures as "the lost sheep of the household of Israel". (Jer 50:6, Matt 10:6, Matt 15:24).
He left in the midst of them a remnant that shall trust in the name of the Lord. The remnant's responsibility is to teach the disobedient spiritual Israel the error of their ways, and pray for their repentance. (Zeph 3:11-13).
When a child of God commits a sin, they die=separate themselves, temporary, from the fellowship of God, until they repent, they do, however, not lose their eternal inheritance.
The inspired scriptures are written to God's born again children, as instructions on how God wants his children to live their lives, while they sojourn here on earth. They are not written to the natural mankind, who cannot discern spiritual things (1 Cor 2:14) to tell them how to get themselves saved eternally.
