Well, that gives people the chance to 'cherry-pick' whatever they like to justify their agendas.
Can I give you an example? I opened the bible to Deuteronomy and snatched the first verses that I saw.
Now, let's say that all the commands in Deuteronomy are those of Jesus, and let's say that these verses ARE TRUE FOREVER.... OK?
These verses allow a husband to drag his wife outside and stone her to death, if she asks him to change faith. A misguided Christian could tell us that this is the wish of the Lord, but I know it is not, because Jesus gave a New Testament and ommitted this stuiff!
So for me, if it is not in the New Testament, it is OUT!
Here is that piece... there are many others:-
What would you think if a neighbouring husband did that to his wife because she found faith in another religion, and then quoted that to you?
Deuteronomy {13:6}
If thy brother, the son of thy mother, or thy son, or thy daughter, or
the wife of thy bosom, or thy friend, which [is] as thine own soul,
entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers; {13:7} [Namely,] of the gods of the people which [are] round about you, nigh unto thee, or far off from thee, from the [one] end of the earth even unto the [other] end of the earth; {13:8} Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him: {13:9}
But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people. {13:10}
And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage. {13:11} And all Israel shall hear, and fear, and shall do no more any such wickedness as this is among you.
