The story of Achan in Joshua 7 is a sobering story of God getting rid of a weak link. Achan took some plunder from Jericho after God said not to.
24 Then Joshua, together with all Israel, took Achan son of Zerah, the silver, the robe, the gold wedge, his sons and daughters, his cattle, donkeys and sheep, his tent and all that he had, to the Valley of Achor. 25 Joshua said, "Why have you brought this trouble on us? The LORD will bring trouble on you today." Then all Israel stoned him, and after they had stoned the rest, they burned them.
Yikes. God, I think, is basically saying, "If the rest of the world is going to know me by my people, I can't have behavior like this."
1st John 3:8 says;
The reason the Son of God appeared was to destroy the devil's work.
One reason Jesus came was to destroy the devil's work. The devil came to destroy our lives through sin & Jesus came to save us from that. Continuing in 1 John 3;
9No one who is born of God will continue to sin, because God's seed remains in him; he cannot go on sinning, because he has been born of God.
John's not talking about being perfect (1:8-10) but sin is not a normal way of life for a Christian. If a Christian has a particular sin in his life, he's going to do something about it; like a good coach or military general from the previous post. If sin is normal in a Christian's life & not dealt with, that person is making a mockery of Jesus' life & mission.
10This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God;
How can a Christian enjoy what God sent Jesus to destroy? I read of a man praying in church, asking God to get rid of the spiritual cobwebs in the member's lives. Then one fella said, "Lord, just kill the spider." That's the mission: destroy, not tolerate. Too often I've just wanted to clean the webs out of the corner to look better & not deal with the spider.
