Well, the opposite of that would be "We are saved by faith alone and is always alone."
So take your pick.
Which one is it?
Redemption, Justification, Sanctification, and Salvation!
Redemption: 100 percent the work of God, thru the life, death, resurrection, and ascension of Jesus Christ! All mankind are redeemed in Christ! Eph 2
Galatians 2:16 3:13
Christ hath redeemed us from the curse of the law...
Christ alone accomplished the redemption of mankind apart from any works on our part!
(Redemption is not Salvation)
Rom 5:10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
Justification: our acceptance of redemption thru faith and baptism! Become a disciple and member of Christ and His Church! Jn 3:5 acts 2:38 Mk 16:16 He who believes and is baptized shall be saved. 1 Corinthians 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit. Galatians 3:27
For as many of you as have been baptized into Christ have put on Christ.
Sanctification: the life of grace in the holy sacrifice of the mass and sacraments, prayer, virture, and good works, the just living by faith, and faith working thru love! Phil 1:29 called to suffer with Christ.
All done in Christ thru His grace! Jn 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
Salvation: a christian in the state if grace at the moment of death we enter into the salvation of the Lord! Mt 24:44-47 faithful servant! Jn 15:1-5 abide in me. Mt 24:13 But he that shall endure unto the end, the same shall be saved.
Heb 3:14 For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;
Heb 6:11 And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end:
Heb 4:14 For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;
Rom 13:11 ...for now is our salvation nearer than when we believed.
Suffering required for glorification with Christ!
Romans 8:17
And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
2 Timothy 2:12
If we suffer, we shall also reign with him: if we deny him, he also will deny us:
Justification and salvation are not the same rom 5:9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
1 Pet 3:20
Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
21 The like figure whereunto even baptism doth also now save us!
(Ark of Noah a type of the church, member of Christ and his church and salvation by baptism!)
(Outside the ark all died and outside the church there is no salvation!)
The holy church is the ark of grace and salvation!
