No I personally didn't say that. I was quoting the words of Jesus, so it was Jesus who said that - Matthew 19:26 (WEB):
(26) Looking at them, Jesus said, “With men this is impossible, but with God all things are possible.”
Jesus was answering the disciples' question, "Who then can be saved?" (verse 25). Luke phrases it differently - Luke 18:27 (WEB):
(27) But he said, “The things which are impossible with men are possible with God.”
So Jesus was probably being specific about the starting question of the passage in verse 16, "what good thing shall I do, that I may have eternal life?" While it may seem impossible for men to do anything to gain eternal life, God is able to provide for us so that we may have eternal life.
However, we are told elsewhere that it is against God's nature to lie:
Titus 1:2 (WEB):
(2) in hope of eternal life, which God, who can’t lie, promised before time began;
Numbers 23:19 (WEB):
(19) God is not a man, that he should lie, nor a son of man, that he should repent. Has he said, and will he not do it? Or has he spoken, and will he not make it good?
God's perfect righteous and loving character, his morals, means that He chooses not to lie, just as we should also choose to not lie. However, He could say He was going to do one thing and then later change His mind:
Exodus 32:9-14 (WEB):
(9) Yahweh said to Moses, “I have seen these people, and behold, they are a stiff-necked people.
(10) Now therefore leave me alone, that my wrath may burn hot against them, and that I may consume them; and I will make of you a great nation.”
(11) Moses begged Yahweh his God, and said, “Yahweh, why does your wrath burn hot against your people, that you have brought out of the land of Egypt with great power and with a mighty hand?
(12) Why should the Egyptians speak, saying, ‘He brought them out for evil, to kill them in the mountains, and to consume them from the surface of the earth?’ Turn from your fierce wrath, and repent of this evil against your people.
(13) Remember Abraham, Isaac, and Israel, your servants, to whom you swore by your own self, and said to them, ‘I will multiply your offspring as the stars of the sky, and all this land that I have spoken of I will give to your offspring, and they shall inherit it forever.’”
(14) Yahweh repented of the evil which he said he would do to his people.
That's why God made a promise and swore an oath in His own name, to give us reassurance in our hope that He would not change His mind - Hebrews 6 (WEB):
(13) For when God made a promise to Abraham, since he could swear by no one greater, he swore by himself,
(17) In this way God, being determined to show more abundantly to the heirs of the promise the immutability of his counsel, interposed with an oath;
(18) that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to take hold of the hope set before us.
(18) No one has seen God at any time. The one and only Son, who is in the bosom of the Father, he has declared him.
That was not God declaring that - it was John!
No, I don't. Jesus said he had seen God and knew God:
John 6:38 (WEB):
(38) For I have come down from heaven, not to do my own will, but the will of him who sent me.
John 6:46 (WEB):
(46) Not that anyone has seen the Father, except he who is from God. He has seen the Father.
John 8:54-55 (WEB):
(54) Jesus answered, “If I glorify myself, my glory is nothing. It is my Father who glorifies me, of whom you say that he is our God.
(55) You have not known him, but I know him. If I said, ‘I don’t know him,’ I would be like you, a liar. But I know him, and keep his word.
Jesus knew his Father intimately, and his character is very much like his Father's. Jesus revealed again God's name (the religious leaders had forbidden anyone to use God's name, which was not God's will) and taught his disciples about God:
Joh 17:25-26 (WEB):
(25) Righteous Father, the world hasn’t known you, but I knew you; and these knew that you sent me.
(26) I made known to them your name, and will make it known; that the love with which you loved me may be in them, and I in them.”
John 14:7 (WEB):
(7) If you had known me, you would have known my Father also. From now on, you know him, and have seen [discerned, perceived] him.”
He doesn't have two natures. He has had a change of nature - twice - but he has only ever had one nature at a time. It's unreasonable, absurd even, to think that any living being could have two natures at the same time. Could you exist as a dog and a tree at the same time? How could that possibly work!
Sharing knowledge is not a nature. That's nonsense!
It's my pleasure to try and help others better understand the truth of God's Scriptures. :)
