Turn to God does not mean we by our own will turn to Him

"Our more subtle adversaries cavil at all these testimonies, because there is no impediment, they say, that prevents our exerting our own ability, and God assisting our weak efforts. They adduce also passages from the Prophets, where the accomplishment of our conversion seems to be divided equally between God and us. 'Turn ye unto me, and I will turn unto you' What assistance we receive from the Lord has already been shown, and needs not to be repeated here. I wish only this single point to be conceded to me, that it is in vain to infer our possession of ability to fulfill the law from God's command to us to obey it; since it is evident, that for the performance of all the Divine precepts, the grace of the Legislator is both necessary for us, and promised to us; and hence it follows that at least more is required of us than we are capable of performing. Nor is it possible for any cavils to explain away that passage of Jeremiah, which assures us, that the covenant of God, made with his ancient people, was frustrated because it was merely a literal one, and that it can only be confirmed by the influence of the Spirit, who forms the heart to obedience. Nor does their error derive any support from this passage: 'Turn ye unto me, and I will turn unto you' For this denotes, not that turning of God in which he renovates our hearts to repentance, but that in which he declares his benevolence and kindness by external prosperity; as by adversity he sometimes manifests his displeasure. When the people of Israel, therefore, after having been harassed with miseries and calamites under various forms, complained that God was departed from them, he replies that his benignity will not fail them if they return to rectitude of life, and to himself, who is the standard of righteousness. The passage, then is miserably perverted, when it is made to represent the work of conversion as divided between God and men. We have observed the greater brevity on these points, because it will be a more suitable place for this argument when we treat of the Law." John Calvin, Institutes. 2. 5. 9.
