Emilia, Katlin, you attend Gateway Church in Southlake Texas but don't know that it is the Gospel that we need to know to be saved. In other words, if you know the Gospel and call yourself a Christian, then you will know that without it, there is no salvation. The Gospel includes what sin is, who we sin against, sin can't be forgiven without a just God to pardon, and His pardon will not come unless you have faith and repent.
No Buddist, Muslim, Mormon, Jehovas Witness, Catholic or whatever else is good enough to go to heaven on their own righteousness.
Read your Bible a lot more to test if you are in the faith.
Here is a very narrow definition of salvation, also make sure you have the right Jesus.
Jesus said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me.
