No, Christians who support gay marriage and gay rights will NOT go to Heaven, because God hates all gay people and God hates every heterosexual who loves gay people.
Heaven is God’s realm, and God will only let those in to Heaven, who hate gay people as people and homosexuality as a practice.
For God, defending gay people is a Capital Crime, punisheable by eternal damnation. That is why everyone who remained in Sodom and Gomorrah were killed by God in Divine Punishment.
When Lot’s wife looked back at Sodom and Gomorrah, God killed her instantaneously. That is how much God hates gay people!
Those who support pro-gay politicians are rejecting the LORDSHIP of Jesus Christ, and they will go to eternal damnation in Hell for this rejection.
When a Christian tells you that he or she is voting for a pro-gay politican, do NOT consider that person a Christian brother or a Christan sister. Ye shall know them by their fruit!
Not all who say “Lord, Lord” will enter eternal life in heaven….
