In Christianity, one must believe in Jesus as our personal Savior to enter Paradise. What does Islām say about Salvation?

Salvation in Islām does not depend on someone else to do it do for us. We are responsible for our deeds and actions preceded by our good intentions. Therefore, everyone has to work hard with good intention. Our intention as Muslims is to please the Creator. Whoever believes in God, in all the Prophets and Messengers that God sent to mankind; in the Day of Judgment; and do good deeds to all without personal ego or without exploitation, then and only then God assures us eternal Salvation. Through His Mercy, Forgiveness and Blessings, people will be given Salvation.
