In the Bible, one reads:
For all have sinned … (Romans 3:23 (NKJV))
“All” casts a broad net. It sweeps up, well, all of us, including all Christians.
That means that all Christians have sinned. If sinning were a race, 100% of those claiming Jesus as their Savior and Lord would have crossed the finish line.
Congratulations, Christians. As a group, you are perfect – you all have sinned.
