Christianity is unlike any other religion. That's because Christ is unlike any other "god."
In many religions, man tries to atone for his sins by doing good works. The more good things he does – so say such religions – the better his chances of being saved from damnation.
That's an awful weight to carry: How does one know when he's done enough good works to be saved?
But Christianity's not like that – thankfully.
In Christianity, sin and its damning effects are acknowledged. Romans 6:23 says "The wages of sin is death . . ." That means our sins will sentence us to damnation.
But God doesn't stop there. He provides a way out of that punishment. That's what the rest of Romans 6:23 says: "The wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord."
In Christianity, men don't try to work toward God. Instead, God does the work. He comes to men, to save them. He initiates and completes that salvation, not man. It's one of the greatest things that separates Christianity from all other religions – and God from all other "gods."
