Is It a Passive Passing Over?

Some have argued that while election to salvation is an active choice on god's part, reprobation is a passive passing over. But in the gospels jesus gives thanks to the father for concealing the things and revealing them to babes. All these elements arear brought together and combined in in the words of jesus himself. They will forever be an antinomy, which is a kind of tension between what is apparently contradictory, but in fact, its resolved in the mind of god.
