Presumably the fact of being a Christian means that gay Christians probably believe in the possibility of going to heaven.
No, Christians do not believe in Jannah, as it is a concept in Islam referring to paradise. Christians believe in heaven as their ultimate destination after death.
There is no evidence for heaven, so it depends on faith. Christians believe you will go to heaven and see God. Atheists believe there is no heaven and no God.
After Jesus died, Christians believe he ascended to heaven to be with God.
Only if they exist. Christians and Muslims believe that both heaven and hell exist, but belief is not proof.
We believe that the people that were obedient to Jesus and God will go to heaven to be with them, to homes that Jesus is preparing for us.
It depends on their religion. Christians believe that they will go to heaven and spend eternity with God. Muslims believe that if they are good enough, they will also go to heaven. Hindus believe that they will 're-transform' into an animal, preferably a cow.
For Christians you go to heaven by believing the gospel, and knowing that Jesus died for us. Learn his word in the Bible. When you dont do that stuff and really believe in him and ask him to be your savior you wont go to heaven.
True Christians (the true servants of God) will go to heaven on Judgment Day.
From their perspective it will be instantaneous.
Christians believe that as long as you ask Jesus to come into your heart and to save you from your sins, than you will go to heaven. Muslims believe you have to earn your way to heaven and do many strange things. catholics believe that you must please God by doing "good works".
Becaus Catholics aren't Christians. Catholics believe that you have to go through the High Priest to talk to God, they believe that you'll go to purgetory if you do something wrong you didn't confess, and they pray to the saints. Christians, on the other hand, don't believe they need to go through someone else to talk to God (Jesus took care of the sepparation), they believe that if you rely on Jesus to get to heaven then you will go to heaven (no pergetory), and they only pray to God because the saints are only human.
People who do not believe in God also do not believe in hell. This is a worry only for Christians.
