Sentry vs Mephistophiles

How does Sentry fair against the devious Mephisto in these scenarios:

1: Mephisto has just taken out the Dark Avengers and Sentry's just stepped in.

2. Sentry, after he's just seen Mephisto kill his wife and try and take her soul in bob's house.

3. Classic Sentry trying to retrieve his wifes soul from Mephisto in his realm

mephisto stomps?....

Just out of curiosity, what powerset has Sentry got, that he could contend with Mephisto, who's at least a mid to high end skyfather level, and has reality warping powers, and can take on the likes of Galactus, without hyperbole lol

Mephisto is below a weak Odin even in hell. Said that he can't match Galactus
