Leviticus 20:7-9

Lev 20:7 Consecrate yourselves, therefore, and be holy, because I am Yahveh your God.
Lev 20:8 Keep my prescriptions and do them; I am Yahveh who sanctifies you.
Lev 20:9 Because anyone who curses his father or his mother will surely be put to death; he has cursed his father or his mother; his blood is upon him.

consecrate or curse

All of the prescriptions of the Mosaic law were linked. That is why the LORD required that the Israelites keep all the prescribed laws in order not to (for example) curse their parents. Ignoring some of the lesser laws would lead to committing a greater offence. He required consecration and he promised sanctification.

LORD, you have saved us by your grace through the death of your Son. Now show us how to consecrate ourselves so that we do not miss out on your sanctification.
