Mark 9:2-10 and Romans 8:31b-34

Mark 9:2-10
2 And his vestments became radiant and exceedingly white like snow, with such a brilliance as no fuller on earth is able to achieve.
3 And there appeared to them Elijah with Moses; and they were speaking with Jesus.
4 And in response, Peter said to Jesus: "Master, it is good for us to be here. And so let us make three tabernacles, one for you, and one for Moses, and one for Elijah."
5 For he did not know what he was saying. For they were overwhelmed by fear.
6 And there was a cloud overshadowing them. And a voice came from the cloud, saying: "This is my most beloved Son. Listen to him."
7 And immediately, looking around, they no longer saw anyone, except Jesus alone with them.
8 And as they were descending from the mountain, he instructed them not to relate to anyone what they had seen, until after the Son of man will have risen again from the dead.
9 And they kept the word to themselves, arguing about what "after he will have risen from the dead" might mean.
10 And they questioned him, saying: "Then why do the Pharisees and the scribes say that Elijah must arrive first?"
Romans 8:31b-34
If God is for us, who is against us?
32 He who did not spare even his own Son, but handed him over for the sake of us all, how could he not also, with him, have given us all things?
33 Who will make an accusation against the elect of God? God is the One who justifies;
34 who is the one who condemns? Christ Jesus who has died, and who has indeed also risen again, is at the right hand of God, and even now he intercedes for us.
