John 3:16
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Even if you aren't religious, you should believe on the name of Jesus and ask him for salvation. You have everything to gain and nothing to lose.
You might say: "this is well and good but I don't believe." The Bible is actually an amazing book. Wise people read the Bible, and once they read they believe.
Romans 10:17
17 So then faith cometh by hearing, and hearing by the word of God.
Jesus Christ will write your name in the book of life and everything will be made known to you in time. The consequences of not accepting salvation so freely given are very severe.
You cannot be saved by your works. You cannot be saved by "being a good person."
Sin is transgression of the law:
1 John 3:4
4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Everyone has sinned:
Romans 3:23
23 For all have sinned, and come short of the glory of God;
The wages of sin is death:
Romans 6:23
23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Revelation 21:8
But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Revelation 20:15
And whosoever was not found written in the book of life was cast into the lake of fire.
But you, Bay-Jirapong, can be saved by the grace of God.
Psalm 103
8 The Lord is merciful and gracious, slow to anger, and plenteous in mercy.
9 He will not always chide: neither will he keep his anger for ever.
10 He hath not dealt with us after our sins; nor rewarded us according to our iniquities.
11 For as the heaven is high above the earth, so great is his mercy toward them that fear him.
12 As far as the east is from the west, so far hath he removed our transgressions from us.
13 Like as a father pitieth his children, so the Lord pitieth them that fear him.
14 For he knoweth our frame; he remembereth that we are dust.
15 As for man, his days are as grass: as a flower of the field, so he flourisheth.
16 For the wind passeth over it, and it is gone; and the place thereof shall know it no more.
17 But the mercy of the Lord is from everlasting to everlasting upon them that fear him, and his righteousness unto children's children;
18 To such as keep his covenant, and to those that remember his commandments to do them.
