'Salvation' in the Bible

I am not ashamed of the gospel, for it is the power of God for salvation [from His wrath and punishment] to everyone who believes [in Christ as Savior], to the Jew first and also to the Greek.

and endurance, proven character (spiritual maturity); and proven character, hope and confident assurance [of eternal salvation].

What shall we say then? That Gentiles, who did not pursue righteousness [who did not seek salvation and a right relationship with God, nevertheless] obtained righteousness, that is, the righteousness which is produced by faith;

For not knowing about God’s righteousness [which is based on faith], and seeking to establish their own [righteousness based on works], they did not submit to God’s righteousness.

For with the heart a person believes [in Christ as Savior] resulting in his justification [that is, being made righteous—being freed of the guilt of sin and made acceptable to God]; and with the mouth he acknowledges and confesses [his faith openly], resulting in and confirming [his] salvation.

So I say, have they stumbled so as to fall [to spiritual ruin]? Certainly not! But by their transgression [their rejection of the Messiah] salvation has come to the Gentiles, to make Israel jealous [when they realize what they have forfeited].

For if their [present] rejection [of salvation] is for the reconciliation of the world [to God], what will their acceptance [of salvation] be but [nothing less than] life from the dead?

Do this, knowing that this is a critical time. It is already the hour for you to awaken from your sleep [of spiritual complacency]; for our salvation is nearer to us now than when we first believed [in Christ].
