Why does one need salvation?

We need salvation because of the sin nature in our hearts! God sent His Son Jesus Christ into the world as a living sacrifice for our sins! He died on the cross for this so we wouldn't spend eternal life in Hell! John3:16 For God so loved the world that He gave His one and ony Son that whoever believes in Him will not perish but have everlasting life.

When God created the world, it was perfect. Everything was good. Then he made Adam and Eve, and gave them their own free will, so they would have a choice whether to follow and obey God or not. But Adam and Eve, the very first people God made, were tempted by Satan to disobey God, and they sinned. This separated them (and everyone that came after them, including us) from being able to have a close relationship with God. He is perfect, and holy, and must judge sin. As sinners, we couldn't make it there on our own. So, God made a way that we could be united with Him in heaven. "For God so loved the world that he gave his only Son, so that everyone who believes in Him will not perish but have eternal life" (John 3:16). "For the wages of sin is death, but the free gift of God is eternal life through Christ Jesus our Lord" (Romans 6:23). Jesus was born so that He could teach us the way and die for our sins so that we would not have to. Three days after His death, He rose from the grave (Romans 4:25), proving Himself victorious over death. He bridged the gap between God and man so that we may have a personal relationship with Him if we would only believe.

No one is perfect. We have all sinned and deserve to rot in hell. We need salvation because we cannot earn our way into heaven.

Because mankind has been enslaved to sin and death ever since Adam and Eve sinned. By excercising faith in Jesus ransom sacrifice and taking in accurate knowledge of him and his Father Jehovah God, we have the chance to live forever as God intended.

I think people want consolation as much as to be saved from their mistakes ("sins"). We'd like to eventually live somewhere where we can be secure in peace and happiness.

to be saved from one's sins which will condem one to hell which can be avoided.
