Hebrews 12:1-4; Hebrews 12:25-29

1 Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, 2 fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God. 3 Consider him who endured such opposition from sinners, so that you will not grow weary and lose heart. 4 In your struggle against sin, you have not yet resisted to the point of shedding your blood.
25 See to it that you do not refuse him who speaks. If they did not escape when they refused him who warned them on earth, how much less will we, if we turn away from him who warns us from heaven? 26 At that time his voice shook the earth, but now he has promised, “Once more I will shake not only the earth but also the heavens.” 27 The words “once more” indicate the removing of what can be shaken—that is, created things—so that what cannot be shaken may remain. 28 Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, 29 for our “God is a consuming fire.”
