John 3:16,Romans 10:9-13, 2 Corinthians 5:17-21

Salvation and Redemption
John 3:16
For God so greatly loved and dearly prized the world that He [even] gave up His only begotten ([a]unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life.
Romans 10:9-13
Because if you acknowledge and confess with your lips that Jesus is Lord and in your heart believe (adhere to, trust in, and rely on the truth) that God raised Him from the dead, you will be saved.

For with the heart a person believes (adheres to, trusts in, and relies on Christ) and so is justified (declared righteous, acceptable to God), and with the mouth he confesses (declares openly and speaks out freely his faith) and confirms [his] salvation.

The Scripture says, No man who believes in Him [who adheres to, relies on, and trusts in Him] will [ever] be put to shame or be disappointed.(D)

[No one] for there is no distinction between Jew and Greek. The same Lord is Lord over all [of us] and He generously bestows His riches upon all who call upon Him [in faith].

For everyone who calls upon the name of the Lord [invoking Him as Lord] will be saved.
2 Corinthians 5:17-21
Therefore if any person is [ingrafted] in Christ (the Messiah) he is a new creation (a new creature altogether); the old [previous moral and spiritual condition] has passed away. Behold, the fresh and new has come!

But all things are from God, Who through Jesus Christ reconciled us to Himself [received us into favor, brought us into harmony with Himself] and gave to us the ministry of reconciliation [that by word and deed we might aim to bring others into harmony with Him].

It was God [personally present] in Christ, reconciling and restoring the world to favor with Himself, not counting up and holding against [men] their trespasses [but cancelling them], and committing to us the message of reconciliation (of the restoration to favor).

So we are Christ's ambassadors, God making His appeal as it were through us. We [as Christ's personal representatives] beg you for His sake to lay hold of the divine favor [now offered you] and be reconciled to God.

For our sake He made Christ [virtually] to be sin Who knew no sin, so that in and through Him we might become [[g]endued with, viewed as being in, and examples of] the righteousness of God [what we ought to be, approved and acceptable and in right relationship with Him, by His goodness].
