Therefore we conclude that a man is justified by faith without the deeds of the law. (Romans 3:28 KJV) According Paul is one justified by faith alone both in Rom 3:38 and also mentioned in Gal 2:16.
The question is, are we saved merely by faith alone just as Paul writes, as also so many I talk to claim.
Scriptures below emphasizes each a different aspect e.g endurance, obedience, by doings and also one verse seems to faith without works while another says with works.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: (Ephesians 2:8)
And being made perfect, he became the author of eternal salvation unto all them that obey him (Hebrews 5:9)
But he that shall endure unto the end, the same shall be saved. (Matthew 24:13)
For not the hearers of the law are just before God, but the doers of the law shall be justified. (Romans 2:13)
By faith alone
Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. (Galatians 2:16)
Not by faith alone
You see that a person is considered righteous by what they do and not by faith alone. (James 2:24)
