Like I implied previously, we don't know the criteria at the personal level.
We weren't there and the Ephesians passage does not give it. The purpose, yes - for the praise of His glory.
The criteria at the individual level. No.
Why Jacob and not Esau? Why you and not your moral Mormon neighbor?
Knowing that criteria (if it is knowable this side of heaven) would stop the C vs A debate (IMO).

But we do know whom God chose and why, it is plainly declared in scripture.
1 Cor 1:17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
19 For it is written,
I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
20 Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world?
21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
22 For the Jews require a sign, and the Greeks seek after wisdom:
23 But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;
24 But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.
25 Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.
26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:
27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
28 And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are:
29 That no flesh should glory in his presence.
30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:
31 That, according as it is written, He that glorieth, let him glory in the Lord.
Who God chooses and why is no mystery as Calivinism teaches, it is plainly declared in God's Word. God chose the foolish to confound the wise, he chose the weak to confound the mighty, he chose those who are base and despised, to bring to nought those that are noble. He did this that no flesh should glory in his presence.
God does not choose a person simply because they are poor, there are poor people who are atheists, or believe false religion. But generally speaking it is the poor and the base, the despised who trust in God. This is a constant theme in the OT, the poor and fatherless were often oppressed and exploited by the rich and powerful, even as they are today.
Psa 10:4 The wicked, through the pride of his countenance, will not seek after God: God is not in all his thoughts.
5 His ways are always grievous; thy judgments are far above out of his sight: as for all his enemies, he puffeth at them.
6 He hath said in his heart, I shall not be moved: for I shall never be in adversity.
7 His mouth is full of cursing and deceit and fraud: under his tongue is mischief and vanity.
8 He sitteth in the lurking places of the villages: in the secret places doth he murder the innocent:
his eyes are privily set against the poor.
9 He lieth in wait secretly as a lion in his den:
he lieth in wait to catch the poor: he doth catch the poor, when he draweth him into his net.
10 He croucheth, and humbleth himself,
that the poor may fall by his strong ones.
11 He hath said in his heart, God hath forgotten: he hideth his face; he will never see it.
12
Arise, O LORD; O God, lift up thine hand: forget not the humble.
13 Wherefore doth the wicked contemn God? he hath said in his heart, Thou wilt not require it.
14 Thou hast seen it; for thou beholdest mischief and spite, to requite it with thy hand:
the poor committeth himself unto thee; thou art the helper of the fatherless.
The rich and powerful have always oppressed the poor and fatherless. These poor and fatherless commit themselves and trust in God for they have no other help. It is these that trust in God that God has chosen.
It is not a mystery whatsoever who God has chosen and why.
