Hebrews 12:1-3 (NIV)
12 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.
Luke 21:25-36 (NIV)
25 “There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. 26 People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27 At that time they will see the Son of Man coming in a cloud with power and great glory. 28 When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.”
29 He told them this parable: “Look at the fig tree and all the trees. 30 When they sprout leaves, you can see for yourselves and know that summer is near. 31 Even so, when you see these things happening, you know that the kingdom of God is near.
32 “Truly I tell you, this generation will certainly not pass away until all these things have happened. 33 Heaven and earth will pass away, but my words will never pass away.
34 “Be careful, or your hearts will be weighed down with carousing, drunkenness and the anxieties of life, and that day will close on you suddenly like a trap. 35 For it will come on all those who live on the face of the whole earth. 36 Be always on the watch, and pray that you may be able to escape all that is about to happen, and that you may be able to stand before the Son of Man.”
