Whether lifeless faith is a gift of God?

Objections

Objection 1 : It would seem that lifeless faith is not a gift of God. For it is written (Dt. 32:4) that "the works of God are perfect." Now lifeless faith is something imperfect. Therefore it is not the work of God.
Objection 2 : Further, just as an act is said to be deformed through lacking its due form, so too is faith called lifeless [informis] when it lacks the form due to it. Now the deformed act of sin is not from God, as stated above (FS, Question [79], Article [2], ad 2). Therefore neither is lifeless faith from God.
Objection 3 : Further, whomsoever God heals, He heals wholly: for it is written (Jn. 7:23): "If a man receive circumcision on the sabbath-day, that the law of Moses may not be broken; are you angry at Me because I have healed the whole man on the sabbath-day?" Now faith heals man from unbelief. Therefore whoever receives from God the gift of faith, is at the same time healed from all his sins. But this is not done except by living faith. Therefore living faith alone is a gift of God: and consequently lifeless faith is not from God.
