True faith is impossible without repentance

What is true repentance?‎

"Repentance is to leave The sins we loved before And show that we in earnest grieve,By doing so no more."

Rom 1:17

For in it the righteousness of God is revealed from faith to faith; as it is written, "BUT THE RIGHTEOUS man SHALL LIVE BY FAITH." 

"Righteousness" is Key word in Romans, used 39 times.

Here Paul means that in the Gospel God reveals how people can become righteous in His sight, how He counts them righteous, makes them righteous, makes them right with Himself.It is altogether by faith

Rom 3;28 For we maintain that a man is justified by faith apart from works of the Law.

When Paul says salvation is through faith he is not excluding repentance. Repentance is a part of true faith in Christ  Rom 2:4,5 

Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing that the

kindness of God leads you to repentance?But because of your stubbornness and unrepentant heart

you are storing up wrath for yourself in the day of wrath and revelation of the righteous judgment of God,

Matt 3:2 "Repent, for the kingdom of heaven is at hand."

Mark 1:15 and saying, "The time is fulfilled, and the kingdom and believe in the gospel." of God is at hand; repent 

True faith is impossible without repentance (Rom 2;4 

Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing thatthe kindness of God leads you to repentance?) And so God's goodness leads to men to repentanceand so faith.

Repentance precedes faith, but is so closely bound up with it thatit might be called the first step of faith.

It is part of the "obedience of faith" 

Rom 1:5 hrough whom we have received grace and apostleship to bring about the 

obedience of faith among all the Gentiles for His name's sake,

Can we imagine that faith is worthy of the name if it lacks this first step?

"Revealed" - a part from God's revelation men could not know the truth about this righteousness.
