Heaven will have anyone that has asked for forgiveness, repented of their sins because they have accepted Jesus Christ as their personal Lord and savior, regardless of denomination. God doesn't care about the labels we put on us, but He does care about the heart.
TNT! Romans 10: 9-10 tells how we are saved, yes room for any who follow this.
9That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.
10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
But if you do not believe the word of God as the true word of God then how can you believe you have done what that word says must be done to be saved? Again, you cannot have it both ways. There is only one way my friend.
