WELCOME TO BEREANS AFLAME
When we say that something or someone is good, exactly to what are we comparing? You don't call a line crooked without first having some idea of what constitutes a straight line, do you? And when you compare yourself to an ultimate good standard, how well do you compare? Are you crooked?
The gospel is the "good news" that though we were yet sinners, Christ lived a pure and righteous life. took the death penalty for our sins that we might become His righteousness - His standard of right.
