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

1 Therefore, since we are surrounded by such a huge crowd of witnesses to the life of faith, let us strip off every weight that slows us down, especially the sin that so easily trips us up. And let us run with endurance the race God has set before us. 2 We do this by keeping our eyes on Jesus, the champion who initiates and perfects our faith. Because of the joy awaiting him, he endured the cross, disregarding its shame. Now he is seated in the place of honor beside God’s throne. 3 Think of all the hostility he endured from sinful people; then you won’t become weary and give up. 4 After all, you have not yet given your lives in your struggle against sin.
25 Be careful that you do not refuse to listen to the One who is speaking. For if the people of Israel did not escape when they refused to listen to Moses, the earthly messenger, we will certainly not escape if we reject the One who speaks to us from heaven! 26 When God spoke from Mount Sinai his voice shook the earth, but now he makes another promise: “Once again I will shake not only the earth but the heavens also.” 27 This means that all of creation will be shaken and removed, so that only unshakable things will remain. 28 Since we are receiving a Kingdom that is unshakable, let us be thankful and please God by worshiping him with holy fear and awe. 29 For our God is a devouring fire.
