Your eternal destiny depends upon your decision.

This is why this concluding section is written as an extended invitation to you to believe in the Lord Jesus Christ, not only as a great teacher and prophet, but as the eternal Son of God, the only Savior of mankind, the final message of God to man.
A desperate man asked the apostle Paul and his fellow worker Silas

"Sirs, what must I do to be saved?" (Acts 16:30).

That man felt the heavy burden of sin, the agony of guilt, and the fear of the coming day of judgment.  He wanted to be saved from all of these.

"Believe on the Lord Jesus Christ, and you will be saved" (Acts 16:31 NKJ)

was the answer of Paul and  Silas.  The desperate man believed and was saved and his heart was filled with joy.
You can do as he did.  Think about Jesus Christ, His sinless life, His love for His enemies, His love for sinners, and His forgiveness.  Think about His death on the cross for you, to pay the penalty for your sins -even before you were born.  He knew everything about you even before your birth.  The prophet David said:

My frame was not hidden from You, when I was made in secret, and skillfully wrought in the lowest parts of the earth.  Your eyes saw my substance, being yet unformed.  And in Your book they all were written, the days fashioned for me, when as yet there were none of them (Psalm 139: 15, 16 NKJ).

You can be saved if you confess your sins to God and put your trust in Jesus Christ and His finished work on the cross.  He said:

I am the Way, the Truth, and the Life.  No one comes to the Father except through me (John 14:6 NKJ).

Jesus Christ is not a way, but He is the only Way.  He does not just tell the truth, He is the Truth incarnated.  He does not point us to life, He is the Life.  The apostle John says:

If we receive the witness of men, the witness of God is greater; for this is the witness of God which He has testified of His Son.  He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son.  And this is the testimony that God has given us eternal life, and this life is in His Son.  He who has the Son has life; he who does not have the Son of God does not have life (I John 5:9-12 NKJ).

The apostle Peter says:

Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved (Acts 4:12 NKJ).

In the Gospel of John we read:

He who believes in the Son has everlasting life, and he who does not believe the Son shall not see life, but the wrath of God abides on Him (John 3:36).

When you believe in Jesus Christ as your Savior and Lord, it means that your name is written in the book of life.  It means you will be with God in heaven on the Day of Resurrection.  You will never enter Hell or pass over it.  On the other hand, you have to expect that while you are on earth you will be persecuted, afflicted, imprisoned, and possibly even executed for the sake of Christ.

For unto you it is given in the behalf of Christ, not only to believe on Him, but also to suffer for His sake (Philippians 1:29).
Yea, and all that will live godly in Christ Jesus shall suffer persecution (2 Timothy 3:12).

Jesus said to His disciples:

These things I have spoken to you, that you should not be made to stumble...  Yes, the time is coming that whoever kills you will think that he offers God service.  And these things they will do to you because they have not known the Father nor Me (John 16:1-3 NKJ).

That is the price of your faith in Jesus Christ, but in all your afflictions for His sake you will never be left alone, you will always feel his presence, for He promised:

Lo, I am with you always, even unto the end of the world (Matthew 28:20).

In addition, you will be rewarded with great reward:

For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us (Romans 8:18 NKJ).

And I saw a new heaven and a new earth:  for the first heaven and the first earth were passed away; and there was no more sea.  And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.  And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain:  for the former things are passed away.  And he that sat upon the throne said, Behold, I make all things new.  And he said unto me, Write:  for these words are true and faithful.  And he said unto me, It is done.  I am Alpha and Omega, the beginning and the end.  I will give unto him that is athirst of the fountain of the water of life freely (Revelation 21: 1, 3-6).

And there shall be no more curse:  but the throne of God and of the Lamb shall be in it; and his servants shall serve him: And they shall see his face; and his name shall be in their foreheads.  And there shall be no night there (Revelation 22:3, 4).

This is the destiny of those who believe in the Lord Jesus Christ.
