Do I know with certainty?

Around midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening. Suddenly, there was a massive earthquake, and the prison was shaken to its foundations. All the doors immediately flew open, and the chains of every prisoner fell off! The jailer woke up to see the prison doors wide open. He assumed the prisoners had escaped, so he drew his sword to kill himself. But Paul shouted to him, “Stop! Don’t kill yourself! We are all here!” The jailer called for lights and ran to the dungeon and fell down trembling before Paul and Silas. Then he brought them out and asked, “Sirs, what must I do to be saved?” They replied, “Believe in the Lord Jesus and you will be saved, along with everyone in your household.” - Acts 16:25-31 (NLT)

Of all the questions that could ever be asked, of all the questions that could ever be answered, none is more important than this one.  What shall I do to inherit eternal life?  That is the most important question that can be asked and answered.  And the reason is that every human soul is immortal.  No soul, no inner person in any human being ever goes out of existence.  Every human being ever born lives forever.  Our bodies die, our souls go on eternally.  We are created immortal.  Annihilation is a lie.  Soul sleep is a lie.  Reincarnation is a lie.  Evolution is a lie.  Every person who has ever lived will be the person they are forever. The only question is, where and under what condition will you spend your forever?  That is obviously the most compelling question that can ever be asked.  And compared to the brief time in which we live in this world, compelling beyond any other consideration.  Every one of us is eternal.  You will go on as you forever.  James says that life in this world is a vapor that appears for a little time and vanishes away.  It's like steam from a boiling kettle, there it is and then it's gone.  Life in this world is an infinitesimal amount of time compared with eternity.  You will live forever.  You will never go out of existence.  And you will spend that forever in one of two places, heaven or hell, and those are the only two places.  There is no other place.  There is no purgatory.  There is no waiting place.  There is no limbo.  There is heaven, and there is hell and that is all and you will be in one of those two places through all eternity.  And you will be conscious that you are there with the full heightening of all your rational faculties running at their maximum.  And there will be no dulling of your sensibilities and sensitivities and understanding and comprehension as if to somehow mitigate the joys of heaven or ameliorate the pains of hell. - John MacArthur

“Don’t let your hearts be troubled. Trust in God, and trust also in me. There is more than enough room in my Father’s home. If this were not so, would I have told you that I am going to prepare a place for you? When everything is ready, I will come and get you, so that you will always be with me where I am. And you know the way to where I am going.” “No, we don’t know, Lord,” Thomas said. “We have no idea where you are going, so how can we know the way?” Jesus told him, “I am the way, the truth, and the life. No one can come to the Father except through me. - John 14:1-6 (NLT)

Jesus went to Galilee, preaching the good news of [the kingdom of] God,  and saying, “The [appointed period of] time is fulfilled, and the kingdom of God is at hand; repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life] and believe [with a deep, abiding trust] in the good news [regarding salvation].” - Mark 1:14b,15 (Amplified Bible)

Do you know Jesus Christ as your personal Savior?

Now I am glad I sent the letter, not because it hurt you but because the pain turned you to God. It was a good kind of sorrow you felt, the kind of sorrow God wants his people to have, so that I need not come to you with harshness. For God sometimes uses sorrow in our lives to help us turn away from sin and seek eternal life. We should never regret his sending it. But the sorrow of the man who is not a Christian is not the sorrow of true repentance and does not prevent eternal death. - Corinthians 7:9,10 (Living Bible)

Do you know with certainty that you will spend eternity in heaven?

God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Salvation is not a reward for the good things we have done, so none of us can boast about it. For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago.- Ephesians 2:8-10 (NLT)

Be Encouraged to know with certainty where you will spend eternity.
