Please show me the scriptures that teach us about God choosing people for salvation.
Here are just some of the more obvious verses that informs us of election. I can provide more if you'd like,
[1Pe 1:2 KJV]
2
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.
[Eph 1:1, 3-5, 7, 11 KJV]
1 Paul, an apostle of Jesus Christ by the will of God,
to the saints which are at Ephesus, and to the faithful in Christ Jesus:
3 Blessed [be] the God and Father of our Lord Jesus Christ, who hath blessed
us with all
spiritual blessings in heavenly [places] in Christ:
4 According as
he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
5
Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, ...
7
In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace; ...
11
In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:
Is obeying the Lord and His commandments required for salvation?
No and only disobedient people are saved which, before becoming saved, we all were. Our actions
in no way dictate, our salvation - it's a free gift given to those whom He has chosen.
Yes.
And having been perfected, He became the author of
eternal salvation to all who obey Him,
Hebrews 5:9
In other words, Christ is the author of eternal salvation - it is not addressing its application but that He is its author
(see Heb 12:2 below). Those who "obey" are those who obey the Gospel of Christ. To be of those, you must first have been called (see 2Th 2:14 below). If you don't obey the gospel of Christ, then, at least up to that point, you haven't been called or saved
[Heb 12:2 KJV] 2 Looking unto Jesus
the author and finisher of [our] faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
[1Pe 1:2 KJV] 2 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.
[2Th 2:14 KJV] 14 Whereunto
he called you by our gospel,
to the obtaining of the glory of our Lord Jesus Christ.
[Rom 1:16 KJV]
16 For I am not ashamed of the
gospel of Christ:
for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
[2Co 4:4 KJV] 4 In whom the god of this world
hath blinded the minds of them which believe not, lest the l
ight of the glorious gospel of Christ, who is the image of God, should shine unto them.
[Rom 1:5 KJV]
5 By whom
we have received grace and apostleship
, for obedience to the faith among all nations,
for his name:
Just as suggestion, but it is never a good idea not to base an entire doctrine on just one verse. In the Bible, we have been admonished that no verse of prophecy is of any private interpretation
