Hebrews 12:25

See to it that you do not refuse (to listen to) Him who is speaking (to you now). For if those (sons of Israel) did not escape when they refused (to listen to) him who warned them on earth (revealing God’s will), how much less we will escape if we turn our backs on Him who warns from heaven?

Rebelling comes in many forms, and not listening to God is one of them. If we step out past God’s will and away when we have been warned not to, we step away from God’s protection and into the hands of the enemy. Just like a parent who warns a child not to go there; it isn’t safe. God warns us for our benefit and to keep us safe and from harm.
