Why humanity needs salvation

Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:

Romans 5:12 (KJV)

God made man to walk with Him. When Adam disobeyed, sin entered the world, and death came with it. Paul does not describe a problem that touches only some people. Death passed upon all men.

That is why being a good person is not enough. Sin is more than the wrong things we do. It is a condition we were born into, and it leaves us separated from a holy God. Romans 3:23 says it plainly: all have sinned, and come short of the glory of God.

The bad news matters because it explains the good news. Nobody looks for a saviour until they know they are lost. We do not tell people they need salvation to shame them. We tell them because God has already done something about it.
