no it is not okay. There is only one name by which people can be saved, Jesus.
People telling you that you can only save yourself is a diabolical lie! The bible tells us repeatedly that you cannot earn your salvation and that salvation is a gift of God. I mean, how good does one have to be to repay God for the death of his son? How much would someone have to do for you to repay you for the death of your son that he killed? Jesus as lord, forgiver of sins and the only path to the father who is God and creator of all; this is your path.
One savior. One God. One way. Jesus.
Believe on Jesus, ask him for forgiveness and to lead your life and be saved. Simple. This is the love of God.
