The gospel is the Word of God which spreads civilization. But without God, people loose respect for human life. And without respect, written laws are useless. The world becomes a world of dogs. Every man for himself.
People have to work together in love and respect to advance civilization.
Lawlessness is a break down in civilization. You may say technological progress is advanced civilization. It is not. A white washed tomb is still a tomb. If a society progresses technologically without love, it tends further and further towards self-destruction.
