"I’m as good as any Christian!"
A Christian, by himself,
isn’t good. Jesus said that only God is good.
The only "goodness," or righteousness, that
the believer has comes from Christ (2 Corinthians 5:21;
Philippians 3:9). The Bible tells us that, without Christ,
man is corrupt and filthy; "there is none that
does good, no, not one" (Psalm 14:3). See also
Romans 3:9 footnote.
