Let's be clear about something: I am an atheist. Religion isn't real. But we're going to set that aside, and look at the specifics of the New Testament.
Does God roll out the red carpet if I watch a crime happen and do nothing?
According to the bible, yes.
So, no where in the Bible does it say you get to go to Heaven. Faith in God and his Grace grants you eternal life. Otherwise you go to the lake of fire.
Ephesians 2: 8-9. "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast."
So, clearly, your actions do not matter. It says it specifically: your works do not get you eternal life. It is a gift. Not earned. It is only the gift of God that grants you eternal life.
Romans backs this up with 6:23: "For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord."
Again, death is the result of sin. We all sinned even before our birth so we're born going to the lake of fire, and ONLY the gift of God's grace gets you eternal life.
Rom. 3:23 backs this up with "For all have sinned and fall short of the glory of God."
Everyone's default state is Sinner and is automatically destined for the lake of fire unless God decides to give you the gift of eternal life.
So...how do you get that gift?
Believe in Jesus. Acts 4:12 says "I am the way, and the truth, and the life. No one comes to the Father except through me.”
Romans 10:9 says the same thing: "Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved."
And, classically, John 3:16-17. "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. 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."
So, all you need to do is 1) say outloud the magic words of Jesus being your lord 2) believe in your heart that Jesus was sent to this world, died for your sins, and was raised from the dead.
That's it.
No good works. No kind heart.
Remember Jesus died for your sins. Not some of your sins. Not an approved list of sins. All your sins. There is no sin to sinny for Jesus to redeem.
The worst person in the world gets eternal life just because they say the magic words and believe it in their heart.
