What is predestination?

A providential arrangement so a person gets full membership in the Church - given without merits, but, it seems from 1 Cor 1and elsewhere, it is given where more is needed. Predestination to heaven is not mentioned in Scripture: however, God lets one go down who gravely and persistently throws away, the only thing that could save him, grace; but then predestines to heaven, without merits, those who do not resist that way. Reason:He wanted to do so in first place, they do not block Him.
