The love, holiness, and integrity of God are in stark contrast with these city-state despots. The God of Israel cannot stand the sight of sin as demonstrated with the sin of Achan. Achan and his family were stoned in an effort to eradicate intentional sin from the midst of Israel. The instructions to wipe out the Canaanite city-states must be understood from this perspective. The holy God of Israel stands against the gods of Canaan and sends his chosen people to cleanse the land from sin before they settle in it. One must think that there is an opportunity to repent, just like with Rahab and be spared of the destruction, but the Canaanites set their face against Israel.
Intentional sin is an abomination to our God. I tend to downplay how pervasive sin really is in my life and of those around me. My tendency is to excuse myself: "After all, I am only human." My humanity should not serve me as an excuse to engage in sin. It should motivate me to seek God all the more and depend on his help to overcome it all the more. The establishment of God's kingdom upon the earth begins with its establishment in my own heart and life. That is my battle day by day. I can do all things through Christ who strengthens me!
Lord, help me in my battle against sin. May I not settle for my sinful nature, but battle against intentional sin to please you and serve you. You have conquered sin and death! Help me enjoy the benefits of such victory through dependent obedience to you.
