I believe most of us would agree that there is a great deal of confusion about salvation, even though God has made it very simple.
The primary reason for all this confusion is the enmity of Satan and his evil angels against God and against humanity. The Devil desires all human being to go to Hell, since he knows it was created for him and his angels.
There is really no need to be confused when we take the total Gospel message and simply believe it. When someone comes along with another gospel, we should ask them a few questions, to which all the answers are "Yes" (according to Scripture):
1. Did Christ die for the sins of the whole world?
2. Does God desire the salvation of all humanity?
3. Are repentance toward God and faith toward our Lord Jesus Christ sufficient to be saved?
4. Is water baptism only for believers and is it a command to every Christian?
5. Does baptism signify that the sinner has died to self and sin, and is totally submitted to God?
6. Is eternal life God's gift to the one who believes?
7. Is the Holy Spirit God's gift to the one who believes?
8. Does salvation include the New Birth, which means that the individual is a new creature in Christ?
10. Are believers predestined and elected to be perfected and glorified?
11. Does that mean that Christians must forsake the ways of the world, and walk in the Spirit by faith?
12. Does salvation include justification, sanctification, and glorification, and are Christians kept by the power of God unto the completion of this salvation?

The Gospel is not clear cut, it can be understood in many different ways. Some say that God chose to save people before they are born as in the "elect of God", others say that only those who follow Christ to the end will be saved. The Catholic Church teaches that there's no salvation outside the Catholic Church.
I don't think that God will hold it against the ordinary person who may have been taught the wrong Gospel. I think those who deliberately teach a false Gospel will be punished, but those who were deceived will be forgiven.
Every denomination convinces their congregation that they teach the true Gospel, only those who have spent many years studying all the different teachings can make an educated decision. The rest of the 1.49 billion Christians don't have the time to spend 3 years in seminary to become Bible scholars.
So I'm pretty sure God takes that into consideration, He expects much of those who have been given much.
