Failures that come back to haunt us...

Manasseh did not drive out the inhabitants of Beth-shean and its villages, or Taanach and its villages, or the inhabitants of Dor and its villages, or the inhabitants of Ibleam and its villages, or the inhabitants of Megiddo and its villages, for the Canaanites persisted in dwelling in that land. When Israel grew strong, they put the Canaanites to forced labor, but did not drive them out completely.
And Ephraim did not drive out the Canaanites who lived in Gezer, so the Canaanites lived in Gezer among them.
Zebulun did not drive out the inhabitants of Kitron, or the inhabitants of Nahalol, so the Canaanites lived among them, but became subject to forced labor.
Asher did not drive out the inhabitants of Acco, or the inhabitants of Sidon or of Ahlab or of Achzib or of Helbah or of Aphik or of Rehob, so the Asherites lived among the Canaanites, the inhabitants of the land, for they did not drive them out.
Naphtali did not drive out the inhabitants of Beth-shemesh, or the inhabitants of Beth-anath, so they lived among the Canaanites, the inhabitants of the land. Nevertheless, the inhabitants of Beth-shemesh and of Beth-anath became subject to forced labor for them.
The Amorites pressed the people of Dan back into the hill country, for they did not allow them to come down to the plain. The Amorites persisted in dwelling in Mount Heres, in Aijalon, and in Shaalbim, but the hand of the house of Joseph rested heavily on them, and they became subject to forced labor. And the border of the Amorites ran from the ascent of Akrabbim, from Sela and upward.
(Judges 1:27-36 ESV)
God's message to the people of Israel had been clear: Drive out all the pagan peoples from the land He had promised.  They failed to do what He said, and ended up with, at the best, a mediocre life, and often, downright disaster. His commands to New Testament followers of Christ also include driving out: driving out the sin that so easily besets us, the thought patterns that distract us, the relationships that pull us down.  Simply put, we are in the situation we are because we have not fully obeyed Him. When we admit that, and stop blaming others, we can take the first steps toward godly change - not before.
