They entered into a covenant to seek the Lord, the God of their ancestors,
with all their heart and soul. All who would not seek the Lord, the God of Israel, were to
be put to death, whether small or great, man or woman. 2 Chronicles 15:12-13
The
Bible does not support killing non-believers just because they don't believe.
In this verse the nation of Israel was killing its own people because
the nation was at a crossroads. These
were their own people who should have been believers. They ones they were killing were those who
brought in the idol worship. According
to Israel’s standards at that time, they were being killed for treason. Today, nations have similar laws for treason
and the death penalty is applied.
This
period of time was a small section of Judah’s history and not a reoccurring way
of life for believers today.
