¶1OPINION
¶2Appellant was convicted of murder and sentenced to 15 years’ imprisonment.
¶3Appellant asserts that the evidence is insufficient to support the conviction because the State’s sole eye witness was unworthy of belief. We must reject the sufficiency of the evidence point if, after viewing the evidence in the light most favorable to the verdict, there is sufficient evidence which, if believed, reasonably supports the finding of guilt. The credibility of witnesses and the weight to be given their testimony are questions which lie within the province of the jury to determine. Combs v. State, 643 S.W.2d 709, 716 (Tex.Crim.App.1982). The testimony of the witness in question, if believed by the jury, is sufficient to support the finding of guilt.
¶4Appellant complains of the trial court’s failure to grant a mistrial after the prosecuting attorney referred to a statement allegedly given to the police by defendant’s wife.
¶5TEX.CODE CRIM.PROC.ANN. art. 38.11 (Vernon 1979) prohibits a wife from testifying against her husband in a criminal case. Indirect use of a spouse’s testimony is reversible error when the action of the State leaves the jury with the impression that the spouse, if permitted to testify, would rebut the testimony of defendant. Johnigan v. State, 482 S.W.2d 209, 210-11 (Tex.Crim.App.1972). In Joknigan, the Court held that a defendant need not object or move for a mistrial where the State is guilty of such misconduct.
¶6The assistant criminal district attorney Sam Ponder, cross-examined appellant as follows:
Q: Isn’t it a fact, Mr. Rodriguez, that you told your wife that you were going to get him?
A: I did not tell her that.
Q: You didn’t tell her that?
A: No, sir, I didn’t.
Q: Okay. And isn’t it a fact that your wife was standing right next to you when you killed John Martinez?
A: That’s a lie.
Q: It’s a lie?
A: Yes, sir.
*736Q: So, you’re aware that your wife gave a statement to the police department to those effects.
¶7The trial court sustained appellant’s objection to this reference to his wife’s statement, but did not grant appellant’s request that the jury be instructed to disregard it and overruled appellant’s motion for mistrial.
¶8The prosecutor’s statement clearly informed the jury that appellant’s wife had told the police that he had told her that he was “going to get” John Martinez.
¶9The State contends that this improper statement to the wife’s statement must be held to be harmless error in view of the other testimony of appellant’s guilt. We disagree.
¶10In determining whether error is reversible, we do not apply the test enunciated in Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979) and followed in Wilson v. State, 654 S.W.2d 465, 471 (Tex.Crim.App.1983) for the purpose of determining whether under the requirements of due process, there is sufficient evidence to justify a rational trier of fact in finding the defendant guilty beyond a reasonable doubt. There is no case, slate or federal, which even suggests that such test is determinative of the question of prejudicial error. To insist that prejudice can be found only when the evidence is insufficient to justify a finding of guilt beyond a reasonable doubt has the effect of precluding a finding of prejudice unless there is no evidence of guilt. If we conclude that the evidence is insufficient to support a finding of guilt, our duty is to reverse and dismiss the case, and inquiry as to the presence of other errors and their prejudicial nature would be a waste of time. Similarly, a finding of sufficiency of the evidence would make it unnecessary to consider other claims of error, since a finding that the evidence is sufficient would necessarily render all other claimed error harmless.
¶11An error can be considered harmless only if it appears beyond a reasonable doubt that it did not contribute to the finding of guilt. Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967). If there is a reasonable possibility that the error contributed to the conviction of appellant, the error cannot be dismissed as harmless. Collins v. State, 602 S.W.2d 537, 538 (Tex.Crim.App.1980).
¶12In this case the appellant, while admitting the killing, claimed that he acted in self-defense. The only witness who contradicted appellant’s testimony was Albert Bautista, who testified that appellant and the decedent engaged in an argument after which appellant, without provocation, stabbed the victim. Appellant’s confession contains no statement inconsistent with his claim of self defense. The testimony of the medical examiner indicates that the deceased had been stabbed in the hand, but such evidence is, at best, neutral with reference to the question of self-defense.
¶13Bautista, the only witness who contradicted appellant’s testimony on the question of self-defense, admitted that he lied “most of the time”; that he was addicted to sniffing paint and that he smoked marihuana. On the night of the killing, he had been sniffing paint and smoking marihuana. It cannot be said that the evidence of such witness is so “overwhelming” as to render harmless the prosecutor’s conduct in calling the jury’s attention to the fact that appellant’s wife had told the police that appellant had expressed to her his intention to “get” the decedent. See Mayberry v. State, 532 S.W.2d 80, 85 (Tex.Crim.App.1975). The statement which the prosecutor improperly attributed to the wife was clearly inconsistent with the claim of self-defense, since it shows a pre-exist-ing intent to kill. If we consider the testimony which would justify a refusal to believe the State’s witness, it cannot be concluded beyond a reasonable doubt that the improper allusion to the wife’s statement did not contribute to the finding of guilt, since such statement furnishes exceedingly strong evidence corroborating the suspect testimony of a paint-sniffing, marihuana-smoking witness who admitted to lying “most of the time.”
¶14*737The judgment of the trial court is reversed and the cause is remanded for a new trial.
