Numbers 15

37 The LORD said to Moses,
38 "Speak to the people of Israel, and tell them to make tassels on the corners of their garments throughout their generations, and to put a cord of blue on the tassel of each corner.
39 And it shall be a tassel for you to look at and remember all the commandments of the LORD, to do them, not to follow after your own heart and your own eyes, which you are inclined to whore after.
40 So you shall remember and do all my commandments, and be holy to your God.
41 I am the LORD your God, who brought you out of the land of Egypt to be your God: I am the LORD your God."
Numbers 15

We are naturally inclined to whore after the desires of the flesh. Active, intentional steps must be taken in order to turn and remember God's holiness--remember Christ--and delight in Him alone.

Work out your salvation with fear and trembling for it is God who works in you. He is able to do far more than we ask or imagine.
