The judge said the prosecution's case is that Johnson "has lied to his girlfriend, to police and to the court".
He reminded the jury that Johnson had admitted lying on eight occasions.
He said: "The prosecution says these lies were told in an attempt to conceal Adam Johnson's guilt."
But he said the defence case was that "such lies as he has told are merely the panicked response of a man who had done wrong by his family".
Judge Rose told the jury it must not assume Johnson is guilty just because he has admitted to lying.
He said: "Lies alone cannot prove a case against Adam Johnson. You must consider all of the evidence in this case."
Johnson, 28, was accompanied by his ex-girlfriend Stacey Flounders, who is the mother of his daughter, as he arrived at Bradford Crown Court this morning.
Miss Flounders revealed the couple had split during her evidence to the court last week, but remain friends. She said she believed Johnson when he said he had only kissed the schoolgirl.
Judge Rose told the jury of eight women and four men: "In February last year, a 15-year-old girl told police that she had met and had intimate relations with the defendant, a professional footballer with Sunderland Football Club.
"The time is fast approaching when you will have to decide whether you are sure that Adam Johnson engaged in sexual activity with the girl."
The judge told the jurors they had to decide whether Johnson put his hand down the girl's trousers and engaged in oral sex.
Judge Rose told the jury that the defence's case is that the girl is a "proven liar who has made up the other allegations".
He said: "It is quite clear, say the defence, that (the girl) is lying."
He said the defence claim Johnson is a "man to be believed", who has suffered "irreparable damage" to his footballing career and his relationship with his girlfriend and mother of his child, Stacey Flounders, as a result of his admissions.
Judge Rose said the prosecution's case is that Johnson, who has admitted being sexually attracted to the girl, is guilty.
He said: "He admits he made contact with her and then met her intending to engage in sexual activity with her. He admits that he kissed her."
The judge said the jury should also take into account the fact that Johnson was previously of good character and that he is now convicted of the two sexual offences to which he has admitted.
He said: "The fact that the defendant pleaded guilty to those two matters is not direct evidence that he committed the offences on this indictment".
The prosecutor in Johnson's case told the jury last week that his was a case of "grooming in its purest form".
Kate Blackwell QC said: "By his own admission, Adam Johnson is not a man of honour.
"He's a self-confessed arrogant man who throws himself at your mercy and asks you to accept that his contrition for what he has done is genuine.
"But we expect you have seen through his transparent cloak of rectitude. It doesn't take much to lift the material and peek inside to the core of deceit and lies."
Miss Blackwell told the court Johnson's claims that the sexual activity had not gone further than a kiss were "preposterous".
She added: "He's a man who has lied and lied and lied again."
Johnson's defence barrister, Orlando Pownall QC, said the girl, who was 'infatuated' with Johnson, had also lied during the investigation.
Mr Pownall ended his speech by urging the jury to acquit Johnson on both counts of sexual activity with a child.
He said: "Mr Johnson is deserving of little, not your sympathy, not your approval in respect of any aspect of his behaviour, but he deserves one thing, if nothing else, and that's a clear and fair, dispassionate consideration by you of all the evidence.
Johnson denies two counts of sexual activity with a child. The jury are expected to be sent out to consider their verdicts tomorrow.
