Because this nation has violated the covenant I ordained for their ancestors and has not listened to me

 Judges 2:6-3:6

Joshua son of Nun, the servant of the Lord, died at the age of a hundred and ten.

After that whole generation had been gathered to their ancestors, another generation grew up who knew neither the Lord nor what he had done for Israel. Then the Israelites did evil in the eyes of the Lord and served the Baals.

In his anger against Israel the Lord gave them into the hands of raiders who plundered them. He sold them into the hands of their enemies all around, whom they were no longer able to resist. Whenever Israel went out to fight, the hand of the Lord was against them to defeat them, just as he had sworn to them. They were in great distress.

Then the Lord raised up judges, who saved them out of the hands of these raiders. Yet they would not listen to their judges but prostituted themselves to other gods and worshiped them. They quickly turned from the ways of their ancestors, who had been obedient to the Lord’s commands.

Therefore the Lord was very angry with Israel and said, “Because this nation has violated the covenant I ordained for their ancestors and has not listened to me, I will no longer drive out before them any of the nations Joshua left when he died. I will use them to test Israel and see whether they will keep the way of the Lord and walk in it as their ancestors did.”  The Lord had allowed those nations to remain; he did not drive them out at once by giving them into the hands of Joshua.

The Israelites lived among the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites. They took their daughters in marriage and gave their own daughters to their sons, and served their gods.

2:3-9 brings us back to the point at which the book of Joshua concluded. V11-23 set out the repented pattern of events which began once the conquest generation had died out. As a result of disobedience, of abandoning God in favor of the local gods, the surrounding nations are not driven out. They remain as a thorn in Israel's side, to test the nation and keep Israel's fighting men well trained in the skills of war.

Why?

God's word is real and true, when the generation of Josua is living, Israelite obey God's word and they knew the grace of the Lord to them. But when the next generation comes they did not know the Lord, so they affected by their environment, the custom of Canaanite, Israelite turn away from the Lord.

This is the sins of the man in the world, but God loves us, there are some judges and God's people on the world to preach God's word and his love. We are the messengers of the Lord.

How?

Preach the love and word of the Lord and let more people join us to honor the holy name of the Lord.
