Mark 11:27-33 and Jude 17, 20-25

Mark 11:27-33
27 And they went again to Jerusalem. And when he was walking in the temple, the leaders of the priests, and the scribes, and the elders approached him.
28 And they said to him: "By what authority do you do these things? And who has given you this authority, so that you would do these things?"
29 But in response, Jesus said to them: "I also will ask you one word, and if you answer me, I will tell you by what authority I do these things.
30 The baptism of John: was it from heaven or from men? Answer me."
31 But they discussed it among themselves, saying: "If we say, 'From heaven,' he will say, 'Then why did you not believe him?'
32 If we say, 'From men,' we fear the people. For they all hold that John was a true prophet."
33 And answering, they said to Jesus, "We do not know." And in response, Jesus said to them, "Neither will I tell you by what authority I do these things."
Jude 17, 20-25
17 But as for you, most beloved, be mindful of the words which have been foretold by the Apostles of our Lord Jesus Christ,
​20 But you, most beloved, are building yourselves up by your most holy faith, praying in the Holy Spirit,
21 keeping yourselves in the love of God, and anticipating the mercy of our Lord Jesus Christ unto eternal life.
22 So certainly, reprove them, after they have been judged.
23 Yet truly, save them, seizing them from the fire. And have mercy on others: in fear, hating even that which is of the flesh, the defiled garment.
24 Then, to him who has the power to keep you free from sin and to present you, immaculate, with exultation, before the presence of his glory at the advent of our Lord Jesus Christ,
25 to the only God, our Savior, through Jesus Christ our Lord: to him be glory and magnificence, dominion and power, before all ages, and now, and in every age, forever. Amen.
