That God can and does thus elevate created nature we know by divine revelation. Jesus Christ is true God and true man in two distinct natures and one person for ever. All the blessed in heaven are affiliated to God after his likeness, in an inferior degree which leaves them in their distinct personalities. This state of glory is properly speaking what is called the kingdom of heaven. Annexed to it, as the proper inheritance of those who share in the royalty of the Son of God, is every kind of the most perfect natural beatitude, in the possession and enjoyment of everything which the universe contains, according to the different natures of men and angels. It is evident, without any reasoning on the subject, that in proposing this supernatural and purely gratuitous beatitude to created beings, God might select whom he pleased as the recipients of so great a grace, and prescribe any conditions which are possible and reasonable for securing its permanent possession. It is perfectly consonant with justice and goodness, that it should be made a prize and reward of merit, and that a state of trial and probation should be appointed for those who were permitted to aspire to this reward. Divine revelation, whose teachings are confirmed by universal experience, makes known to us, that in fact God did place the angels, and afterwards mankind, in a state of probation for this supernatural destiny. A probation must be real and not illusory. It involves the possibility and danger of failure. It must have a prescribed period for each individual and for the whole number. When this period is finished, those who have failed are by the very terms of the probation finally excluded from the hope of retrieving their loss. Divine revelation informs us that the probation of the angels was terminated long ago, and resulted in the winning of eternal beatitude by a certain number and the loss of it by the others. One among the chiefs of the angelic hierarchy rebelled against God and drew after him many other spirits, and with these fallen angels for his ministers and associates, he has continued and will continue on the earth the revolt he began in another sphere, until the day appointed for the final judgment. He has continued it on this earth, by seducing men to join in his rebellion, and making war against Jesus Christ and his kingdom, the universal church. The conditions of human probation are of a very special and peculiar nature, in accordance with the specific nature of mankind, which is extremely different from that of the angels. The angels, as pure spirits and having a simple, intellectual essence, were created singly, and in the actual possession from the first instant of existence of their complete being. Man was made a rational animal, by the law of his nature increasing numerically by generation, and progressing from an inchoate state to his perfection through gradual and successive stages of growth. The first progenitors of the race alone,
