We just read Matthew 1:18~2:12 and Luke 2:1~20 with our children. They KNOW John 3:16.
We know we deserve "the wages of sin" but are offered the gift of grace.
That's the first verse I learned as a kid - John 3:16. Today it is Judge not least you be judged, be relative and silent. Of course we are to make a righteous judgment (right judgment). That's not mentioned.
