Whether Baptism produces its effect when the insincerity ceases?

Objections

Objection 1 : It seems that Baptism does not produce its effect, when the insincerity ceases. For a dead work, which is void of charity, can never come to life. But he who approaches Baptism insincerely, receives the sacrament without charity. Therefore it can never come to life so as to bestow grace.
Objection 2 : Further, insincerity seems to be stronger than Baptism, because it hinders its effect. But the stronger is not removed by the weaker. Therefore the sin of insincerity cannot be taken away by Baptism which has been hindered by insincerity. And thus Baptism will not receive its full effect, which is the remission of all sins.
Objection 3 : Further, it may happen that a man approach Baptism insincerely, and afterwards commit a number of sins. And yet these sins will not be taken away by Baptism; because Baptism washes away past, not future, sins. Such a Baptism, therefore, will never have its effect, which is the remission of all sins.
