Salvation is simple. Gospel is called good news or glad tidings, literally "blessed sound" in Chinese.
Romans 10:15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!

The Bible centres on salvation.
John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
James 1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
1 Peter 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.

To become Christian, one should get to know some basic things about Jesus. A proper object of faith is needed.
Acts 28:31 Preaching the kingdom of God, and teaching those things which concern the Lord Jesus Christ, with all confidence, no man forbidding him.
2 Corinthians 11:4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
2 Corinthians 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?

Do not frighten yourself into rejecting salvation by thinking that you will be unable to repent. Actually it is easier to repent after salvation. In New Testament, if you are saved, then the Holy Spirit dwells in you to strengthen you and shall not leave. Being saved is being born again. Being born cannot be undone.
John 3:7 Marvel not that I said unto thee, Ye must be born again.
John 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
Ephesians 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,

1. to preach the gospel.
2. to check if one person truly believes all the points in the gospel, especially before baptism.
3. as a statement of faith.
4. to protect against heretical doctrines. The conditions for salvation are something cults do not want people to know. Cults even create their own bible to conceal these. If these are not causes for salvation, cults will not bother about them.
5. to find the right church.

Conditions for salvation

   1. Any person with sin shall be with the fallen angels in eternal punishment. (verses)
2. Know about Jesus:
   1. Heavenly Father is God and is called God. (verses)
   2. Jesus Christ is fully God and fully man but uncreated. (verses)
   3. Holy Spirit is God. (verses)
   4. Father, Jesus and Spirit (Father is not Jesus, Jesus is not Spirit and Spirit is not Father) coexist as one and only God who created the world. (verses)
   5. Jesus is the Christ and the Son of God. (verses)
   6. Jesus incarnated to be a sinless man born of a virgin conceived by Holy Spirit. (verses)

   1. Admit you have sinned. (verses)
   2. Be willing to start repenting immediately. (verses)
   3. Accept Jesus as your Saviour. (verses)

What to do after believing

1. Start repenting. For example, if you have taken something that is not yours and that thing is still with you, get rid of it (not giving away as gift in your name). If you are addicted to drug, throw away the drugs and cut the supply. If you gamble, stop it. If you use pirated software tool, stop it. If you are unable to repent, then your faith is not pure yet and you are not saved yet. No excuse. It is not that one cannot repent but actually one does not want to repent. It is correct to say that perhaps a saved person will sin again in future but it is wrong to say that the person does not have to deal with own current sins. After repenting, you will feel clean. If you do not repent, no matter how many times you confess your sin, you will still have guilt.
   James 2:20 But wilt thou know, O vain man, that faith without works is dead?
2. Resist sins to glorify God and feel the joy. You are not alone in doing this because Holy Spirit is in you strengthening you. Confess to God and repent if you fail to resist sin. After being saved, it does not mean you will never sin again, but your resistance to sin will grow. Such resistance should be 'trademark' for Christians. Do not take sinning for granted. Avoid going to places where temptation may be. Do not sin knowingly. Do not plan to sin. Do not think to sin first and confess later. After sinning, there are consequences. You will not be joyful for a long time and you will still have to face punishment in this life by society law and by God. How will you feel if you are sinning when the rapture takes place?
   1 Corinthians 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
   1 Thessalonians 4:5-6 Not in the lust of concupiscence, even as the Gentiles which know not God: That no man go beyond and defraud his brother in any matter: because that the Lord is the avenger of all such, as we also have forewarned you and testified.
   Titus 1:16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
   Hebrews 12:4 Ye have not yet resisted unto blood, striving against sin.
   Hebrews 12:6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.
   Jude 1:4 For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
3. Find a church that accepts all the salvation conditions above and is near to your house to attend every Sunday. Listening to sermon every week will have you reminded regularly of not sinning. It is good to know a few nearby churches that have different service times so that in case you cannot attend one service, you can still go to another.
   Hebrews 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
4. Pray always. Prayer can be done anytime anywhere in the heart. If you do not know how to pray, at least pray before a meal by thanking Heavenly Father in the name of Jesus or simply thanking God. If someone is having the meal with you, ask for permission first before praying.
   1 Thessalonians 5:17 Pray without ceasing.
   
5. Read the Bible when you feel to.
6. Preach the gospel when you feel to. But do not persuade or urge others.
   1 Corinthians 7:15 But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God hath called us to peace.
7. Get baptized after repenting of all your sins you know and completing Sunday school.
8. Help others, especially those who need spontaneous help from good Samaritan, such as a traffic accident victim.

Things that do not affect salvation

You do not have to be able to recite all the points in the gospel but just believe in them. If you yourself are sure that you believe all points in the gospel, then you can be sure you are saved. Do not be influenced by some people who cast uncertainty by saying "you cannot be sure because only God has authority over one's salvation".

Faith saves.
Luke 23:42-43 And he said unto Jesus, Lord, remember me when thou comest into thy kingdom. And Jesus said unto him, Verily I say unto thee, To day shalt thou be with me in paradise.
Romans 13:11 And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Hebrews 10:39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.

1. Sinner's prayer with a preacher, church attendance and baptism. Rituals are observed out of appreciation for salvation, not to acquire salvation. Of course those must still be done if physically able so that other people are more satisfied about your salvation but those must not be done (especially on the person you have just met) before checking acceptance of all points in the gospel. Please forgive the person who judges that you are not Christian on the reason of you have not done those yet. Is a mute person unsaved yet if there is nobody who knows sign language to lead him or her in sinner's prayer?
   Romans 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
   Galatians 2:16 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.
2. Good work. It is instead an output after salvation.
   Matthew 7:17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
   Galatians 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
   Romans 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
   Ephesians 2:9 Not of works, lest any man should boast.
   Titus 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
3. Admitting sins to anybody. If you want to confess your sins, do it to God.
4. Finishing reading the Bible or any other book.
5. Reciting or chanting Jesus' name or Bible verses.
   Matthew 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
6. Speaking in tongue.
