Stamp - Nobody deserves Heaven

Not just that, we all deserve HELL in fact. Because everyone has sinned at least once against God. 

God made it that way, He is a just God and made Hell so that no imperfect thing can enter Heaven but for justice sake get their true reward in Hell for disobeying the ultimate ruler!
So actually we are all destined to go to hell. Being a "good person" won't save us, because we have already done wrong and we still struggle daily. 

BUT, because and ONLY because God is so loving He sent His only son down to earth to live a PERFECT life and die as a sacrifice to take OUR sins on Him, so we could be forgiven and be free from going to Hell.
To be forgiven we must accept that Jesus did die for our sins, be willing to turn away from all the wrong in our life and live a life such as God wants you to live.(The Bible is full of it).

So we must understand that it's nothing WE did that made us worth dying for. God just loved us so much that He died for us. 

John 3:16
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.

Romans 6:23
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord

Romans 5:8
But God shows his love for us in that while we were still sinners, Christ died for us.

Ephesians 2:8-9
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Not of works, lest any man should boast.
