Ok, I guess.
No, I don't think I am wrong about the change of nature.
I think that you and I are using a different definition for the term "nature".
I am meaning "what something is". As in, we are human beings, we have always been human beings, we will always be human beings. That is our nature.
What you are describing above with our change of hearts and becoming more like Christ is all true.
But that doesn't make us "not humans". It makes us better, more perfected humans. But we always remain human.
To change our human nature would mean that what was once human is no longer human because it has become something else.
Hi Bard, Jesus had a human nature too, he had a will, that he denied to do Gods will, it says in the Bible that he was tempted in all points as we are. He was human too like we are he couldn't be tempted if he didn't have a human nature. Also, he would have had an advantage over us, he couldn't come here and tell is to turn from sin, deny ourselves, bare our cross and follow him if he couldn't sin, because he wouldn't have had a human nature like us, so how can he come here, unable to sin, and tell us to follow him, he had to be like us to do this. and he couldn't have overcome Satan and expect us to do the same if he didn't have to go through what we do. And this is why he is our perfect example, because he could sin, but he didn't, not once, Satan did everything he could to try to get him to, but he didn't and in doing so he overcame his evil with good, it says in the Bible that he began to do and teach, he didn't just teach the gospel, he lived by it himself too, and his way is the way to follow.
He is the way, the truth and the life. And he said have no fear, for I have overcome the world. And he will help those who truly repent and turn from this world of sin, willing to become living sacrifices, to lay down their lives and do the will of God, to do the same.
And to do this, is to be willing to die the death, willing to let our old life go, and do the will of God and truly follow Jesus. And when God is ready, he will bless us with his Spirit and teach and guide us everyday in our hearts and minds, and once we are born of God, then the life of Christ will be made manifest in our hearts by the spirit and we too will then bare witness to the truth.
Having a changed heart and a nature more like Christ, full of love, compassion and forgiveness toward others, and bring the love and the word of God to others with the hope that they will want to hear and believe and let Christ in us do his work, and reconcile as many to God as possible through us.
We are to love our God with with all our hearts and minds, soul and strength, and our neighbours as ourselves, and lay down our lives for others and do his will, and if we truly love him, we will. And to do this is to truly follow Jesus Christ.
