If they are a Christian, yes!
Yes, you can still go to heaven if you habitually sin. If a person believes in God, accepts him into their heart, and really tries to live like him (even with flaws), they can still go to heaven.
if Adam and Eve did not sin a person would live for eternity, but they did and technically a person can still live forever but they won't and can live up to 1 century if they are lucky
No, not at all. Sin, by definition is the willingness of a person to do something against the will of God.
If they continue to sin then the person themselves is denying God (that which is good and holy). God is not denying, he is being denied.
Catholics view sin as an act that God finds offensive. Catholics believe there are two types of sin, venial and mortal. Whereas a mortal sin takes a person out of God's graces, a venial sin does not. Catholics believe that all sins can be forgiven by God; no sin is too big for God to forgive.
God ALWAYS forgives you if you are sorry for your sins.
No, Jesus is the Son of God/God and is sinless. He hates all sin, but will forgive sin when a person repents of their sin and accepts Jesus Christ as Savior
save from sin
It wasn't the type of sin that made him flood the earth, it was the fact that everyone was sinning and no one was worshiping God. The reason why he saved Noah and his family was because they were the only ones considered worthy enough to live since they still worshiped God.
Yes, god forgives everyone who asks and repents; however, you will live a easier life not in sin.
Your living arrangements have nothing to do with your relationship with God and Christ. While there are many that would consider it a sin to live together out of wedlock, God is the one that will determine what is and is not a sin and whether it can be forgiven or not.
God treats all killing like a sin, even if you didn't mean it. God still loves those you are killing, no matter what or who they are.
