Salvation is a free gift given to those that believe in Jesus.No, because every verse of Scripture is true, but not every verse has written the whole gospel, doctrine, and prophecy of Scripture.
Every verse of Scripture must be studied, believed, and taught in context of all Scripture from Genesis - Revelation. If any true verse of Scripture is left out of the true gospel and Jesus Christ, then it's a cursed gospel diminishing Scripture of God.
Deu 4:2
Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the LORD your God which I command you.
Those who diminish repentance from dead works for Jesus' sake, also diminish keeping His commandments, as being hearers of His words only, and not doers.
So you would disagree with each of these verses, because they don't include grace? Neither ought they be disagreed with, because they don't include repentance.
They should be believed as true with repentance and grace. Nor can they be done without repentance and grace.
Ezek 18:31
Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die, O house of Israel?
Luke{13:2}
And Jesus answering said unto them, Suppose ye that these Galilaeans were sinners above all the Galilaeans, because they suffered such things? I tell you, Nay: but, except ye repent, ye shall all likewise perish.
So, do you disagree with theses verses, because they don't include 'doing nothing' to be justified by faith-alone? Or, do you agree with the Scriptures that unless we also repent, we will perish like any unrepentant sinner on earth?
Mat 4:17
From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
The gospel of Jesus Christ begins with repentance from sinning against Him.
Mark{1:15}
The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
Acts 3:19
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
2 Cor 7:10
For godly sorrow worketh repentance to salvation not to be repented of:
No one can believe the gospel, be converted to, nor saved by Jesus Christ, without first repenting of sinning against Him.
Heb 6:1
Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
The first principle of the gospel of Jesus Christ is repenting from dead works, to have faith toward God. No one can have the faith of God to go on to perfection and resurrection unto life, without first repenting.
Any gospel diminishing or disannulling repentance from all sins and trespasses, as being unnecessary to believe, be converted, saved, and resurrected from the dead in Jesus' likeness, is another gospel of unrepentant sinful man's own making-alone.
No amount of wrangling by you or anyone else can change that.
Romans 6:23
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
On believing in Jesus for our salvation then we are given the Holy Spirit.
Ephesians 1:13
In Him, you also, after listening to the message of truth, the gospel of your salvation, having also believed,
you were sealed in Him with the Holy Spirit of promise.
2 Corinthians 1:21-22
Now He who establishes us with you in Christ and anointed us is God, who also sealed us and gave us
the Spirit in our hearts as a pledge.
Ephesians 4:30
Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
Salvation is a FREE GIFT and cannot be earned.
The Christian life is another subject altogether that allows us to remain in that saved state.
Salvation is a free gift secured by GRACE through faith and that belongs to Christ alone.
