We cannot. We must immerse ourselves in the Gospels, understanding that the words of Christ are real, true, exact. Christ is God, the Second Person in the Blessed Trinity.
Those who do not take His words seriously do not believe Christ is God Incarnated.
Here are some of the passages for meditation and boldface highlights are mine:
"22 And they were astonished at his doctrine. For he was teaching them as one having power, and not as the scribes.
23 And there was in their synagogue a man with an unclean spirit; and he cried out,
24 Saying: What have we to do with thee, Jesus of Nazareth? art thou come to destroy us? I know who thou art, the Holy One of God.
25 And Jesus threatened him, saying: Speak no more, and go out of the man.
26 And the unclean spirit tearing him, and crying out with a loud voice, went out of him.
27 And they were all amazed, insomuch that they questioned among themselves, saying: What thing is this? what is this new doctrine? for with power he commandeth even the unclean spirits, and they obey him."
That is from Mark 1:22-27. Here are some others.“It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God” Matthew 19:24.”
“Think not that I am come to send peace on earth; I came not to send peace, but a sword” Matthew 10:34.
“Another of his disciples said unto him, Lord suffer me first to go and bury my father. But Jesus said unto him, Follow me; and let the dead bury the dead” Matthew 8:21.
“All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother’s womb; and there are some eunuchs, which were made eunuchs of men; and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive it, let him receive it” Matthew 19:11-12.
“Be ye therefore perfect, even as your Father which is in heaven is perfect” Matthew 5:48.
And, perhaps the hardest saying from Christ, as so many people do not believe this, from John 6.
"51 I am the living bread which came down from heaven.
52 If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world.
53 The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat?
54 Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you.
55 He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day.
56 For my flesh is meat indeed: and my blood is drink indeed.
57 He that eateth my flesh, and drinketh my blood, abideth in me, and I in him.
58 As the living Father hath sent me, and I live by the Father; so he that eateth me, the same also shall live by me.
59 This is the bread that came down from heaven. Not as your fathers did eat manna, and are dead. He that eateth this bread, shall live for ever.
60 These things he said, teaching in the synagogue, in Capharnaum.
61 Many therefore of his disciples, hearing it, said: This saying is hard, and who can hear it?
62 But Jesus, knowing in himself, that his disciples murmured at this, said to them: Doth this scandalize you?
63 If then you shall see the Son of man ascend up where he was before?
64 It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you, are spirit and life.
65 But there are some of you that believe not. For Jesus knew from the beginning, who they were that did not believe, and who he was, that would betray him.
66 And he said: Therefore did I say to you, that no man can come to me, unless it be given him by my Father."
