Gerhard: one grace, worked in believers and repelled by unbelievers
Thesis III. This can be found in Johann Gerhard, theologian of Jena, in his second tome, in the treatise on free choice, chapter 6, section 1. 'We readily grant,' he writes, 'that many resist the Holy Spirit as he undertakes the work of conversion, reject God's counsel against themselves, and judge themselves unworthy of eternal life, so that by their own fault they drive the grace of conversion away from themselves.
Yet we deny that grace itself must for that reason be split into sufficient and efficacious, because the grace of God that works in believers and the grace that unbelievers drive away are one and the same.'

III. Istud videre est apud Joannem Gerardum Theologum Jenensem tomo secundo tractatu de libero arbitrio capite sexto sectione prima. Concedimus, inquit, sane spiritui sancto conversionis opus aggredienti multos resistere, consilium Dei adversus seipsos spernere, & seipsos vita aeterna indignos judicare, atque hac ratione sua culpa gratiam conversionis a se repellere: sed propterea ipsam gratiam in sufficientem & efficacem dividendam esse negamus, siquidem una eademque Dei gratia est, quae in credentibus operatur, & quae ab incredulis repellitur.
