God does in fact demand perfection.
No He does not and you have no verse that says that God demands perfection or you would have quoted one. I know Him pretty well and Jesus, who was like the Father, also did not demand perfection. He said he who gave a disciple of his a cup of cold water will not lose their reward...does not sound like perfection...just a cup of cold water.
Of course, He provided Christ's perfect life, given as a propitiation; so the requirement of perfection is satisfied in Christ's shed blood.
Please show me the scripture that says Jesus told people that he was perfect.
Jeremiah 17:9 is not in scripture?
There is more than one verse in the Bible.
By all means, expound on Jeremiah 17:9 and tell us what it really means.
First of all, Jeremiah 17:9 is a verse in the Bible. So, what it teaches is taught by the Bible. No context is going to nullify the plain meaning of any verse. Every verse in the Bible is a statement of truth.
Blessed is the man who trusts in the LORD,
(there are those who trust in the Lord)
whose trust is the LORD.
8He is like a tree planted by water,
that sends out its roots by the stream,
and does not fear when heat comes,
for its leaves remain green,
and is not anxious in the year of drought,
for it does not cease to bear fruit.”
(does not describe a desperately wicked person)
9The heart is deceitful above all things,
and desperately sick;
who can understand it?
(Jeremiah is not making a statement but asking a question...WHO can understand it)
10“I the LORD search the heart
(the answer: The Lord knows the heart)
and test the mind,
b (hummm, God is testing the mind/heart....hmmm, why if it is desperately wicked, what can be learned by testing if the answer is a given)
to give every man according to his ways,
(Ah, God does not think all people are wicked and their ways are wicked but looks to see what the ways are)
according to the fruit of his deeds.”
(Ah, God does not think all people are wicked and their ways are wicked but looks to see what the fruit of his deeds are)
The conclusion you come up with is NOT what God thinks. Now, as I said, you have decided this is what you WANT TO THINK and so refuse to read any verse, including the rest of Jeremiah 17, to have the scripture teach you and correct your thinking. But I answer for anyone else who is tempted to take ONE VERSE and build a whole theology upon it.
