I believe what is written in Scripture. You can read it for yourself.
You are wrong about this; Scripture is truth.
Are you not aware that even the devil uses Scripture? How, then, can you claim that Scripture is truth?"
MATTHEW 4:5-6
5 Then the devil taketh him up into the holy city, and setteth him on a pinnacle of the temple,
6 And saith unto him, If thou be the Son of God, cast thyself down: for it is written,
He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone.
PSALMS 91:12
12 They shall bear thee up in their hands, lest thou dash thy foot against a stone.
That is why he was telling the Lord Jesus to do what the devil thought was the truth.
However, the truth is God's revelation of the truth in His Word, and not merely what is written.
Therefore, the Lord Jesus portrayed the devil as one in whom there is no truth, even though the words he spoke were taken from Scripture
JOHN 8:44
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because
there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Therefore, your declaration that 'Jesus is Lord' would not be regarded as truth by the Lord, since it is merely your own statement.
However, if those who truly follow the Lord Jesus, or those whom He has chosen, declare that 'Jesus is Lord,' the Lord will accept it because what they say is a revelation from God to them and does not originate from themselves.
