What good is religion if it fails to benefit all mankind?

The purpose of "religion" is to attempt to reach up to God. Religion does not try to benefit mankind.

The bottom line of all man's religions is to be good enough to appease God.

Basically they are "works" based. If I do the right thing, say the right things, think the right things, act the right way then God will have to accept me into His heaven.

The problem with works based religions is, how much is good enough to appease a totally Holy and totally Righteous God?

Sadly all religions fail to benefit mankind.

But God did make a way for us to be acceptable to Him, and that way is through a relationship with His Son, Jesus Christ. The Bible says that God loved us so much the He gave His only Son, that whoever believed in Jesus would have everlasting life (John 3:16). Not works based but Faith based, faith in Jesus and His work for us on the cross. Accepting His work that was exactly what God wants. His righteousness in exchange for our sin. His perfect life for our imperfect lives.
