Throughout history man has looked heavenward and wondered about life after death. Is there a life, is there a resurrection, is there something out there other than a meaningless emptiness or nothing? Do we live now and then nothing?
And if there is an afterlife, then how do we obtain it?
The Apostle Paul had a conversation with a Philippian jailer, who had asked:
Acts 16:30 Then he brought them out and said, “Sirs, what must I do to be saved?” 31 And they said, “Believe in the Lord Jesus, and you will be saved.
And that is the quick and brief answer, and a complete answer, for that matter, of how a person can be saved.
There are many religions out there in the world, but they all reject or ignore Jesus Christ.
Christianity is the only faith, the only philosophy, the only religion (if you are going to call it that), that promotes the truth, which is, Jesus Christ is God. Jesus Christ came to this earth and became a man. And, being true humanity and true deity, He is both God and man in one person, the unique person of the universe.
Romans 5:9 Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God.
1 Thessalonians 5:9 For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ,
Romans 6:23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
Ephesians 2:4 But God, being rich in mercy, because of the great love with which he loved us, 5 even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved
John 14:6 Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.
John 3:15-17
15 that whoever believes in him may have eternal life.
16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. ESV
Because God is perfection, and fair, then He applies His perfect Righteousness and Justice to all of life.
Man is a sinner and imperfect. Something that is imperfect cannot have a relationship with something that is perfect.
And certainly nothing that is evil, sinful, criminal, self-righteous and so forth can raise itself up to a level of perfection, which is sin free. And God who is perfect is not going to lower His perfect standards, is not going to allow sin or arrogance, or lust or anything which is imperfect, to enter into His policies of perfection.
