But if he was perfect, doesn't that mean that it would be impossible for him to sin? God can't sin because He has a perfect nature so if the angel had a perfect nature then he shouldn't have been able to sin...
Free will means the ability to make choices, even bad ones. Its why Adam and Eve could choose to disobey. That is why God had laws written....so that in our fallen, imperfect state, we would choose to do the right thing and stay out of trouble.
How can a human with an imperfect nature, live a sinless life?
Since the sin we inherited from our first parents is in our DNA, it is impossible for us to live a sinless life. That's why we are covered by Jesus sacrifice. His blood is a 'propitiation', which means it covers our sin over like a blanket....like it never happened. It is totally forgivable as long as we are sincerely repentant and try hard not to repeat our mistakes. God does not expect us to do the impossible. Paul knew this. (Romans 7:14-25)
But Satan, the other rebellious angels and unrepentant humans are all spiritual beings who are disobedient but will live forever in hell...
This is not a Bible teaching. It is another adoption by Christendom to scare the pants off little children and gullible adults, so that they could control them. There is no such place as hell. Everlasting life is promised only to the righteous....why would God grant everlasting life to the wicked, only to torture them...he is not a fiend! He has no need to do any of that...he will just leave them in death, never to see life again.
Hell in the Bible is "sheol" (Hebrews) or "hades" in Greek. Neither is a place of torment.....it is a place where the dead sleep. (Ecclesiastes 9:5; 10)
Again I suspect Trinitarians will say that the Trinity is impossible for humans with a limited understanding to fully comprehend.
And doesn't the Bible talk about a Godhead?
They will try to justify their doctrine because their entire belief system rests on it. But the Bible does not mention a "godhead" at all. This is a mistranslation, like the word "hell". According to Liddell and Scott’s
Greek-English Lexicon, the·oʹtes (the nominative form, from which
the·oʹte·tos is derived) means “divinity, divine nature.” (Oxford, 1968, p. 792) Being a true “divinity,” or of a “divine nature,” does not make Jesus as the Son of God, coequal and coeternal with the Father. He clearly said that the Father was greater than he was.
So praise and worship is ultimately just obedience?
We honor God by our obedience and we bring praise to him by allowing him to mold our personality despite all the rot going on around us. This is the mark of a true Christian....being able to hold to the principles that God's word teaches in spite of all the influences around us to do the opposite.
I read recently where many in the churches are succumbing to the world's standards, watching pornography, being entertained by extremely violent or spiritistic movies and computer games...which often glorify bloodshed, satan and demonism. Many are approving of SSM as well. How foolish to fall for the bait. The fallen flesh is no match for the devil without God's spirit. (Proverbs 3:5-6)
Fair point but TBH if I don't know if Unitarians or Trinitarians have it correct since both sides have good points.
It is up to you to check these things out for yourself. Only you can makes decisions about your future. What God is offering is nothing like life in this world.
Rather than offer life to everyone without condition, God sets reasonable conditions for our salvation. After all, life was conditional right from the beginning.....it was a simple case of 'obey and live...disobey and die'. They were the only two choices back then. What choices do we have today? Its a minefield....but not one where there is no safe path out. We have a map and a compass.
I hope your journey is successful.
