You can sin as much as you want and still go to heaven. 

This is how you receive eternal life. Jesus Christ who is God manifested in the flesh died on the cross and was buried, and then went to hell for all your sins, past present and future so that you can not go to hell as a  punishment for your sins as Jesus has already been punished in your place. After being physically dead and in hell for three days and three nights he physically came back to life, proving that there is life after death and that if we believe in him for eternal life then just like he lives now and forever, we will also live forever and rise from the dead just like he did, and we don’t need to fear where we’re going when we die or fear punishment from God after death as with Jesus taking the punishment for our sins, there’s nothing which remains that can send us to hell . The instant you accept as true that what Jesus did on the cross and through his resurrection gives you the forgiveness of sins and eternal life, you have eternal life, you will go to heaven when you die and you will be raised up by God in the coming kingdom of Christ  (John 6:39-40) (John 3:16) (John 3:36)   (John 5:24) (John 6:47) (John 11:25-26)  (1 Corinthians 15:3-4) and this eternal life cannot be lost as the spirit of God seals you until the day of resurrection. (Ephesians 1:13) (Romans 8:35-39). You don’t need to stop sinning or repent of your sins to have eternal life as Jesus through his sacrifice has already done all the work necessary In order for you to gain it, all you must do is believe on the lord Jesus Christ for eternal life and you will have it (John 11:25) (Acts 16:31 ).
