Genesis 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Again, as you rightly say, the Bible says nothing about going to heaven.Rather it says exactly the opposite.
John 3:13 And no man hath ascended up to heaven...
But it does say a lot about men being ‘saved’ if they believe and obey the gospel.
Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
‘Shall be saved’ is referring to being saved from death by resurrection from the dead at an appointed day in the future.
The hope of the gospel is resurrection from the dead.
1 Corinthians 15:12 Now if Christ be preached that he rose from the dead, how say some among you that there is no resurrection of the dead? 13 But if there be no resurrection of the dead, then is Christ not risen: 21 For since by man came death, by man came also the resurrection of the dead. Philippians 3:11 If by any means I might attain unto the resurrection of the dead.
Romans 5:19 For as by one man‘s disobedience many were made sinners, so by the obedience of one shall many be made righteous.
John 15:13 Greater love hath no man than this, that a man lay down his life for his friends. 14 Ye are my friends, if ye do whatsoever I command you.
Psalms 37:9 For evildoers shall be cut off: but those that wait upon the LORD, they shall inherit the earth.
Psalms 37:11 But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
Psalms 37:22 For such as be blessed of him shall inherit the earth; and they that be cursed of him shall be cut off.
Matthew 5:5 Blessed are the meek: for they shall inherit the earth.
Paul explains exactly what is to happen.
1 Corinthians 15:22 For as in Adam all die, even so in Christ shall all (that is – all those baptised into Christ) be made alive. 23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming. 24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. 25 For he must reign, till he hath put all enemies under his feet. 26 The last enemy that shall be destroyed is death.27 For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him.28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
Numbers 14:21 But as truly as I live, all the earth shall be filled with the glory of the LORD.
Matthew 6:10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
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;20 And he shall send Jesus Christ, which before was preached unto you:21 Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
I hope this helps.
