I address this questions to brothers and sisters who are liberals, do you believe that people who don't follow Christianity and don't believe in Jesus (Eg: Muslims, Hindus, Buddhists, Agnostics, Atheists, Baha'is, Animists Jews, etc.) can be saved Even if they never believe in Christianity? Or Salvation can only be found within Christianity??
Paul
directly answers this in Romans chapter 2, verses 6-16, for which it's very helpful to have a few different translations, because of the wording. The NIV is good:
Romans 2 NIV
(but one reading it for the first or 2nd time may want to try several different translations and look up some commentary also).
6 God “will repay each person according to what they have done.”
a 7 To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life.
8 But for those who are self-seeking and who reject the truth and follow evil, there will be wrath and anger.
9 There will be trouble and distress for every human being who does evil: first for the Jew, then for the Gentile;
10 but glory, honor and peace for everyone who does good: first for the Jew, then for the Gentile.
11 For God does not show favoritism.
12 All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law.
13 For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous.
14 (Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law.
15 They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.)
16 This will take place on the day when God judges people’s secrets through Jesus Christ, as my gospel declares."

Also, many interpret what Peter told us in 1rst Peter chapter 3, about how Christ descended to the "spirits in prison" to make proclamation to them (to mean bring them the gospel) to be not only for the instance given, those from before the Flood, but those being only an example, and it meaning all who never heard the gospel.
18 For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit.
19 After being made alive,
d he went and made proclamation to the imprisoned spirits—
20 to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built. ...

This is meant to help add more of scripture, to the truths already stated above. What we know: mortals here are incompetent to judge the salvations of others.
