Jesus never told us to get our scriptures from (or listen to as I think you may have meant) the Bible only.
Like I stated many churches are teaching away from Gods word. When a church tells its members they no longer need to keep Gods commandments and gives members select scriptures taken out of context to support this unbiblical theory its taking people away from God. Jesus kept all of His Fathers commandments and asked all of us to do the same:
John 15:10 If you keep My commandments, you will abide in My love, just as I have kept My Father’s commandments and abide in His love.
This is one example of churches teaching outside the Bible that is not taught in scriptures.
For the record, Jesus did use scriptures when teaching and we are told to follow Him:
Mathew 4:4 But He answered and said, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’ ”
Mathew 4:7 Jesus said to him, “It is written again, ‘You shall not tempt the Lord your God.’ ”
Mathew 4:10 Then Jesus said to him, “Away with you, Satan! For it is written, ‘You shall worship the Lord your God, and Him only you shall serve.’ ”
Mathew 5:21 “You have heard that it was said to those of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’
Mathew 5:33 33 “Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform your oaths to the Lord.’
There are many other examples, these verses are all references to the OT.
2 Timothy 3:16 All Scripture
is given by inspiration of God, and
is profitable for doctrine, for reproof, for correction, for instruction in righteousness,
Isaiah 8:20 To the law and to the testimony! If they do not speak according to this word,
it is because
there is no light in them.
Proverbs 3:5 Trust in the Lord with all your heart,
And lean not on your own understanding;
Mathew 15
8 ‘These people draw near to Me with their mouth,
And honor Me with
their lips,
But their heart is far from Me.
9 And in vain they worship Me,
Teaching
as doctrines the commandments of men.’ ”
I think the scripture has made it abundantly clear we are to only follow Gods words and not mans. God bless
