Hebrews 12:15, 25

See to it that no one falls short of God’s grace; that no root of resentment springs up and causes trouble, and by it many be defiled

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 will we escape if we turn our backs on Him who warns from heaven? [Heb 2:1-4]
