Numbers 33:55 But if ye will not drive out the inhabitants of the land from before you; then it shall come to pass, that those which ye let remain of them shall be pricks in your eyes, and thorns in your sides, and shall vex you in the land wherein ye dwell.
This is a picture of what happens when you tolerate little sins and temptations. God wanted them to separate completely. They didn’t want to do so. He said that if they didn’t then these temptations would make them miserable.
That is what happens with us when we do not get rid of things that might be bringing us down. What is it that keeps you from serving God? What is it that is making your heart cold? Is it the love of money? Is it porn? Separate yourself!
If you do not get hurt your children might!
