Context

“. shall enjoy abundance without fear of evils." Now fear is opposed to hope by opposition of good and evil, as stated above (Q. 23, A. 2; Q. 40, A. 1) , and therefore the fear which will remain in glory is not opposed to hope. In the lost there can be fear of punishment, rather than hope of glory in the Blessed. Because in the lost there will be a succession of punishments, so that the notion of something future remains there, which is the object of fear: but the glory of the saints has no succession, by reason of its being a kind of participation of eternity, wherein there is neither past nor future, but only the present.” source
