1 Timothy 1

1Paul, an apostle of Jesus Christ by the commandment of God our Saviour, and Lord Jesus Christ, which is our hope;

2Unto Timothy, my own son in the faith: Grace, mercy, and peace, from God our Father and Jesus Christ our Lord.

3As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,

4Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.

5Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:

6From which some having swerved have turned aside unto vain jangling;

7Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.

8But we know that the law is good, if a man use it lawfully;

9Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,

10For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;

11According to the glorious gospel of the blessed God, which was committed to my trust.

12And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry;

13Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief.

14And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus.

15This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.

Titus 1:9
holding fast the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict.

1 Corinthians 1:18
18 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19 For it is written:
"I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate."[c]

20 Where is the wise person? Where is the teacher of the law? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? 21 For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.

1 Corinthians 15:1-8,
1 Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, 2 by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain.
3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He rose again the third day according to the Scriptures,

so what does the bible say about the conditions of man, the state man is in after the fall, what is his nature and will ?

Mark 7:21 For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery

Jeremiah 17:9
"The heart is more deceitful than all else And is desperately sick; Who can understand it?

John 8:34
Jesus answered them, "Truly, truly, I say to you, everyone who commits sin is the slave of sin.

So man is a slave to his nature, and mans nature is to sin to rebel against God,No one seeks after God, No one is righteous No not One.

Since we are sinners, we are incapable of removing the guilt of our sinfulness through our own efforts. Gal. 2:21 says, "...if righteousness comes through the Law, then Christ died needlessly." The Law is the dos and donts of moral behavior. In other words, we cant become righteous by what we do. Why? Because we are dead in our sins (Eph. 2:3).

This means that since we cannot remove our own sins, God must do it.

Jesus, who is God in flesh (John 1:1,14; 8:58; Col. 2:9), bore our sins in His body on the cross (1 Pet. 2:24). He died in our place. He paid the penalty of breaking the Law of God that should have fallen upon us. He satisfied the law of God the Father by dying on the cross.

It is only through Jesus that we can escape the penalty that God will execute upon all who have broken his holy and perfect law. Do you want to be saved from the righteous judgment of God? If so, if you want to become a Christian and follow God, then you must realize that you have sinned against God, and are under his judgment. You must look to Jesus who died on the cross and trust what he did in order for you to be forgiven of your sentence and be saved from the judgment of God.

Warnings About
'Another Gospel' Which is Not a Gospel
One of the beautiful and joyful aspects of the message of salvation in Christ that makes it such good news is the element of grace (Acts 20:24). Salvation is the free gift of God to be received by faith alone in Christ alone (Rev. 21:6; 22:17; Rom. 4:4-5; Eph. 2:8-9; Tit. 3:4-5). But the message of grace goes contrary to the heart and thinking of man who intuitively thinks in terms of merit. So, the apostle warned of those who offer a gospel of works for salvation rather than grace. We should remember, as Paul teaches us in Romans 4 and 11. If it is by grace, it is no longer by works and if by works, it is no longer by grace (see Rom. 4:3-4; 11:6). So in reality, any time someone offers a gospel of works, it is not the gospel—a message of good news. Instead it is bad news, it is false, and a terrible distortion.

1:6 I am astonished that you are so quickly deserting the one who called you by the grace of Christ and following a different gospel— 1:7 not that there is another gospel; but there are some who are disturbing you and wanting to distort the gospel of Christ. 1:8 But even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be condemned to hell! 1:9 As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell! 1:10 Am I now trying to gain the approval of people or of God? Or am I trying to please people? If I were still trying to please people, I would not be a slave of Christ (Gal. 1:6-10).

Therefore, if distorted by rejection of the truth that all God does for us in Christ is by grace alone through faith apart from works or by a denial of who Jesus is, then the "gospel" is a "different gospel, which is in fact, no gospel at all (Gal. 1:7)."
