It doesn’t say we were granted belief/given belief, it says we were graciously allowed/granted “to believe”! We are given the opportunity to believe and the opportunity to suffer for the name.
Secondly, the two scenarios, belief/suffering, are linked together, so if belief is given effectually, then why isn’t suffering also effectually given to every believer?

Calvinists interpret the granting (enabling) of faith as an instilling, transferring, infusion of faith
Dort takes this stand
The Canons of Dort
ARTICLE 14
Faith is therefore to be considered as the gift of God, not on account of its being offered by God to man, to be accepted or rejected at his pleasure, but because it is in reality conferred upon him, breathed and infused into him; nor even because God bestows the power or ability to believe, and then expects that man should by the exercise of his own free will consent to the terms of salvation and actually believe in Christ, but because He who works in man both to will and to work, and indeed all things in all, produces both the will to believe and the act of believing also.

Chapter XI. Of Justification Westminster Confession of Faith Chapter XI, 1
THOSE whom God effectually calleth he also freely justifieth; not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous: not for any thing wrought in them, or done by them, but for Christ’s sake alone: not by imputing faith itself, the act of believing, or any other evangelical obedience, to them as their righteousness; but by imputing the obedience and satisfaction of Christ unto them, they receiving and resting on him and his righteousness by faith: which faith they have not of themselves; it is the gift of God.
The Larger Catechism Westminster Larger Catechism Question 77
A. Although sanctification be inseparably joined with justification, yet they differ, in that God in justification imputeth the righteousness of Christ;t in sanctification his Spirit infuseth grace, and enableth to the exercise thereof; in the former, sin is pardoned;w in the other, it is subdued: the one doth equally free all believers from the revenging wrath of God, and that perfectly in this life, that they never fall into condemnation;y the other is neither equal in all, nor in this life perfect in any,a but growing up to perfection.
