"Then you shall again discern between the righteous and the wicked, between one who serves God and one who does not serve Him." Malachi 3.18Did you see the difference between Noah and his generation?
Between Abraham and his family?
Between Isaac and Ishmael?
Between Jacob and Esau?
Between Joseph and his brothers?
Between Moses and the rebellious children of Israel?
Between Joshua/Caleb and the other cowardly spies?
Between Rahab, the prostitute, and the people of Jericho?
Between Gideon and the other children of Israel?
Between David and Saul?
If you haven't been able to see the difference yet, read the books of the prophets and Acts of the Apostles. Certainly you will understand the true difference between those who serve the Living God and those who do not serve Him.
