What is the single best reference that you have?
The Bible, from Genesis 1:1 through Revelation 22:21.
But I will pass along one passage in particular.
Ephesians 1:3-14
Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:
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:
having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
to the praise of the glory of his grace, wherein he hath made us accepted in the beloved.
In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;
wherein he hath abounded toward us in all wisdom and prudence;
having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:
that in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
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:
that we should be to the
praise of his glory, who first trusted in Christ.
In whom ye also trusted, after that
ye heard the word of truth,
the gospel of your salvation: in whom also after that
ye believed,
ye were sealed with that holy Spirit of promise,
which is the earnest of our inheritance until
the redemption of the
purchased possession, unto the
praise of his glory.
(
emphasis mine)
Let's see what the consistent thread through this passage is:
God hath blessed,
In
Christ,
He hath
chosen,
Before the foundation of the world,
In
love,
Predestinated us,
Unto
adoption, (the child does do not do the adopting, the parent does)
By
Jesus Christ,
To
Himself,
Good pleasure of
His will,
His grace,
He hath made us accepted,
His blood,
Forgiveness of sins,
His grace,
He hath abounded,
His will,
His good pleasure,
He hath purposed,
He might gather,
Predestinated according to the pleasure of
Him,
His own will,
His glory,
Sealed with that
Holy Spirit, (the sealer does the sealing, not the object being sealed)
Purchased possession,
His glory.
So salvation is all about God's grace, God's actions, God's choosing, God's predestinating, God's pleasure, God having abounded, God's purpose, God's gathering, God's will, God's glory.

I will continue:
"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." Ephesians 1:11
By these words the apostle brings before our eyes God's omnipotent power as carrying into effectual performance the counsel of his own will towards the objects of his distinguishing favour. An especial blessing is couched in this. Next to a believing view of the purposes of God's grace, and a sweet persuasion of our interest in them, nothing is more strengthening and encouraging than a realizing apprehension of the power of God to carry them into full execution.
Feeling, as we do, our own miserable helplessness, sinking under the pressure of our daily weakness, mourning over continual failures, and grieving on account of perpetual backslidings - encompassed by foes, and distressed by fears - how strengthening it is to our faith, thus tried to the utmost, to believe that he who has purposed has power to perform. This persuasion of the almighty power of God was the support and strength of Abraham's faith, which bore him up in the face of seeming impossibilities, and whereby he gave glory to God, (Romans 4:18-21).
When, then, as walking in the steps of the faith of Abraham, we can look up believingly to the God and Father of the Lord Jesus Christ, as we behold sovereign grace in his heart, and infinite wisdom in his mind, so we see almighty strength in his arm. We become sweetly persuaded that all which his loving heart feels, his infinite wisdom directs and his omnipotent power will unfailingly execute.
