HINES, Justice.

This Court granted certiorari to the Court of Appeals to consider whether a criminal defendant who is on first offender probation that has not been discharged or revoked can be sentenced as a recidivist under OCGA § 17-10-7 (b) (2) when he is subsequently convicted of a violent felony. In this case, both the trial court and the Court of Appeals determined that Davis could be so sentenced. See Davis. v. State, 239 Ga. App. 318 ( 521 S.E.2d 368) (1999). For the reasons that follow, we reverse.

In 1991, Davis was sentenced as a first offender for armed robbery and possession of a firearm during the commission of a crime. See OCGA § 42-8-60 et seq. His eligibility for discharge of his first offender's probation would not arise until 2001. In 1997, he was convicted on charges of armed robbery and possession of a firearm during the commission of a crime; these charges were unrelated to the acts underlying the 1991 charges, and occurred during the period of his first offender probation. The court sentenced Davis to life without parole under the provisions of OCGA § 17-10-7 (b) (2), which states in pertinent part:

"Any person who has been convicted of a serious violent felony in this state or who has been convicted under the laws of any other state or of the United States of a crime which if committed in this state would be a serious violent felony and who after such first conviction subsequently commits and is convicted of a serious violent felony for which such person is not sentenced to death shall be sentenced to imprisonment for life without parole."

Davis contends that his 1991 guilty pleas to armed robbery and possession of a firearm during the commission of a crime cannot serve as a basis for sentencing under OCGA § 17-10-7 (b) (2) because he did not stand "convicted" on those charges. That is correct.

"A first offender's guilty plea does not constitute a `conviction' as that term is defined in the Criminal Code of Georgia (OCGA § 16-1-3 (4)) . . ." Davis v. State, 269 Ga. 276, 277 (2) ( 496 S.E.2d 699) (1998). See also Priest v. State, 261 Ga. 651, 652 (2) ( 409 S.E.2d 657) (1991). Criminal statutes must be strictly construed against the State. Fleming v. State, 271 Ga. 587, 590 ( 523 S.E.2d 315) (1999). For a defendant to be sentenced as a recidivist under OCGA § 17-10-7 (b) (2), after a first "conviction" for a violent felony, he must be convicted of a subsequent violent felony. Under the first offender statute, until an adjudication of guilt is entered, there is no conviction. See Davis, supra. Therefore, Davis was not convicted in 1991.

The Court of Appeals cited Scott v. State, 216 Ga. App. 692, 694 (4) ( 455 S.E.2d 609) (1995), for the proposition that "[a] prior first offender record may be used to sentence a defendant as a recidivist for a later crime except where the conditions of probation attendant to such record have already been fulfilled so that the defendant has been discharged without an adjudication of guilt pursuant to OCGA § 42-8-62 (a)." Davis, 239 Ga. App. at 319 (2). However, the Court of Appeals misreads Scott. In that case, the first offender probation had been completed and Scott had been discharged. The opinion properly held that the first offender guilty plea was inadmissible in aggravation, just as it would be to show that Scott was a recidivist; the opinion is silent as to any application of a first offender guilty plea to a recidivist sentence when the first offender probation has been neither revoked nor completed.

The fact that Davis was convicted in 1997 does not automatically change the nature of his 1991 first offender treatment. "There is no provision for revocation of first offender status by operation of law." Brantley v. State, 242 Ga. App. 85, 88 (2) (S.E.2d) (2000). The statutory scheme grants first offender probation status and eventually the probation is either revoked or it is discharged; unless it is revoked, there is no conviction. Revocation of the first offender probation status is necessary to constitute a "conviction" under OCGA § 17-10-7 (b) (2), and that did not occur here. The subsequent conviction does not necessarily result in a revocation of Davis's probation status. Upon a violation of a first offender's terms of probation, the trial court "may" enter an adjudication of guilt; it is not obliged to do so. OCGA § 42-8-60 (b). See Bliss v. State, 244 Ga. App. 160 ( 535 S.E.2d 251) (2000), formulating a rule for the exercise of that discretion. In fact, despite the later conviction, failure of the State to initiate any revocation proceedings against Davis, and failure of the court to revoke the probation, would result in Davis's completion of the probationary period, and his discharge from probation. See Mills v. State, 268 Ga. 873, 874-875 ( 495 S.E.2d 1) (1998).

Under the first offender statute, the case "has, in effect, been suspended" during the period of probation. State v. Wiley, 233 Ga. 316, 317 ( 210 S.E.2d 790) (1974); State v. Boyd, 189 Ga. App. 617, 618 ( 377 S.E.2d 11) (1988). Davis's 1991 first offender probation had not been revoked prior to his 1997 convictions, and therefore had not become convictions. Compare Daniels v. State, 271 Ga. 167 ( 517 S.E.2d 66) (1999). Thus, in 1997, he had not previously been convicted of a violent crime and could not be sentenced as a recidivist under OCGA § 17-10-7 (b) (2).

Judgment reversed. All the Justices concur.
