Mechanics of Salvation - Propitiation / Substitution
Atonement: Propitiation (for Wrath of God); Substitution (for Sin of Man)
And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. (1 John 2:2 KJV)
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (2 Corinthians 5:21 ESV)
Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father: (Galatians 1:4 KJV)
Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. (1 Peter 2:24 KJV)
For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit, (1 Peter 3:18 ESV)
Therefore, He had to be like His brothers in every way, so that He could become a merciful and faithful high priest in service to God, to make propitiation for the sins of the people. (Hebrews 2:17 HCSB)

Legality of Salvation - Redemption
Jesus cancelled the record of our sin by His death, nailing it to the cross.
Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins. (Hebrews 9:22 ESV)
And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. (Colossians 2:13-14 ESV)
In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace (Ephesians 1:7 NIV)

He was able to do so because He entered the real sanctuary in heaven.
For Christ did not enter a sanctuary made with human hands that was only a copy of the true one; he entered heaven itself, now to appear for us in God’s presence. Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. Otherwise Christ would have had to suffer many times since the creation of the world. But he has appeared once for all at the culmination of the ages to do away with sin by the sacrifice of himself. Just as people are destined to die once, and after that to face judgment, so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him. (Hebrews 9:24-28 NIV)

The death of Christ completely propitiate the wrath of God and nothing else is needed.
"Τετέλεσται (It is finished)" John 19:30
τετέλεσται
τε - reduplication prefix, done in the Greek perfect tense
τελεσ - Greek perfect tense stem of τελεω which means "I finish, fulfill"; the noun version is τελος, which means "end, goal"; perfect tense is translated in English using "has been (done)"
ται - third person singular ending, or "he/she/it", depending on context

Glory of Salvation - Reconciliation
All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. (2 Corinthians 5:18-19 ESV)

Motivation of Salvation - God's Love
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. (John 3:16 KJV)
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. (Romans 5:8 NIV)
Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. (1 John 4:10 KJV)

Proof of Salvation - Works / Fruit
But someone will say, "You have faith and I have works." Show me your faith apart from your works, and I will show you my faith by my works. You believe that God is one; you do well. Even the demons believe - and shudder! Do you want to be shown, you foolish person, that faith apart from works is useless? (James 2:18-20 ESV)

Purpose
But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: (1 Peter 2:10 KJV)
