>It's true. Jesus wasn't even declared
lol try reading , this sounds like the best declaration anyone could have
[Mat 3:17 KJV] 17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
>and I've read it several times.
then you should have come across this several times
[Rom 5:8 KJV] 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Some have argued on the basis of it's Jewish characteristics that it was written in the early church period, possibly the early part of AD 50 when the church was largely Jewish and the gospel was preached to Jews only.
[Gal 5:6 KJV] 6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.

This was exactly what you were asking for. There are many more examples. I suggest you do a word search here : https://www.blueletterbible.org
and place the word "love" in the search tool and then review all the results. Trust what you read because God does not lie like Satan or man.
Jesus did not sin. That is known given even by idiots. Sorry I did not point that out for you.
