There is life after death, and it is eternal. But do not think that everyone is going to heaven. There is a place filled with fire and brimstone called the lake of fire.
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. " (underline added for emphasis)
Romans 3:23, "For all have sinned, and come short of the glory of God;"
Romans 6:23a, "For the wages of sin is death,.."
Psalm 14:1, "The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good. "
Psalm 58:3," The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies."
Hebrews 10:31, "It is a fearful thing to fall into the hands of the living God. "
But God made a way of hope and escape.
Romans 5:6,7, "For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. "
Isaiah 7:14, "Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel. "
Isaiah 9:6, "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. "
John3:16, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlating life."
Romans 14:9, "For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living. "
John 10:15, "As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. "
John 10:27- 30, "My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
I and my Father are one. "
How do you become God's sheep? Repent (say the same thing that God says) and believe.
Matthew 4:17, "From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand. "
John 3:16, "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."
Romans 10:9, "That if thou shalt confess with thy mouth the Lord Jesus, an believe in thine heart that God hath raised him from the dead, thou shalt be saved."
You cannot get saved with works. Ephesians 2:8,9, "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
