According to Protestantism, are we saved by faith into a repentance of law-following? Just have a question regarding faith and works:
A person has eternal life solely by faith in Jesus Christ (as in believing every word Jesus said, including his claims that he is God), but by believing that Jesus is God, the person also believes that following the law is what he/she should do, and thus the person repents; which is why although John and Romans quote salvation is by faith alone, Jesus urged in Matthew, Mark and Luke for people to repent, and James says that faith without works is dead.
According to Protestantism would the above view be correct?
Although it is true that Christians believe salvation comes through faith in Jesus Christ, it is not true that Christians believe they are under the Mosaic Law.  Jesus came to fulfil the Law and has introduced a new covenant.  The new covenant frees us from an obligation to keep the hundreds of laws that were given to Israel.  The new covenant is not a covenant of works (obeying the Mosaic Law).  Christians have been liberated from the condemnation of the Mosaic Law and have been set free by the grace of God and are “born again” – the spiritual rebirth that gives us life.

For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it (James 2:10).


Therefore no-one will be declared righteous in [God’s] sight by observing the law; rather, through the law we become conscious of sin (Romans 3:20).

When people repent, before God, and seek His forgiveness, it is because the Holy Spirit has convicted them of their sinful condition.  They realise (as I did, 25 years ago) that Jesus died in order to pay the penalty of sin – of all sin.  It is our sins that nailed Jesus to that instrument of torture.  God, in His infinite wisdom, grace and love, provided the solution to sin.  He sent His one, His only-begotten Son, to redeem us from the penalty of death that comes with our inability to keep God’s laws.
Your question is based on a wrong premise.  You say, “By believing that Jesus is God, the person also believes that following the law is what he/she should do.”  By believing that Jesus died to pay the penalty of sin (which is spiritual death as well as physical death) the person who repents comes to understand that it is faith that saves us.  And, as the Bible says, even faith is a gift from God.

But when the kindness and love of God our Saviour appeared, he saved us, not because of righteous things we had done, but because of his mercy.  He saved us through the washing of rebirth and renewal by the Holy Spirit, whom he poured out on us generously through Jesus Christ our Saviour, so that, having been justified by his grace, we might become heirs having the hope of eternal life (Titus 3:4-7).

The deity of Jesus has nothing to do with following the Mosaic Law.  When I turned to God in faith I didn’t even know that Jesus subsists in the One Being of God. It took some time before I fully understood who Jesus REALLY was.  That lack of understanding did not prevent me from realising that I had to repent and turn to God and seek forgiveness.
I am a Christian of the Protestant persuasion.  I have been set free and have been adopted into God’s family, not because of anything I could ever do, but because I have faith in Christ Jesus, and am eternally indebted to what God, in Jesus, accomplished in order to save a sinner such as me.
