Andreas of Caesarea : Peter says that God has blessed us greatly and that he has done so through his Son. Furthermore, he says that those who receive these things are those who are protected in the power of God, as Christ himself prayed: "Holy Father, protect them." If the inheritance is kept in heaven for believers, some grow cold thinking that it has been left for us in the earthly Jerusalem, assuming that the rewards of the kingdom will be acquired by the appearance of luxury every thousand years. They should be asked why they say that this bodily luxury is immortal and unfading but at the same time they limit it to every thousandth year. They need to be told that these words show that the inheritance is in the kingdom of heaven and that it cannot be known by the senses of mortal beings. We have been assured that we shall receive all these great things by the Father himself, who is the one who gives them. For it is certain by other means also that he will bless us with these things through his own Son, and not simply through the Son but through his resurrection. For if everything has been granted to us, what is there left to give? The inheritance is immortal and unfading, and what is even greater, it is not here on earth but in heaven. — CATENA Bede : You who are kept by the power of God through faith, etc. And the Lord said in the Gospel: In my Father's house are many mansions (John XIV). And again: It is not mine to give to you, but for whom it is prepared by my Father (Mark X). Therefore, seats are prepared in the kingdom of God, mansions prepared in the house of the Father, salvation prepared in heaven, only let him render himself worthy who desires to receive it. But since no one can make himself worthy solely by his own effort, nor can come to eternal salvation by his own strength, it is rightly prefaced: You who are kept by the power of God through faith. For no one can sustain themselves in good by their own free will's power, but help must be sought from Him through all things, that we may be perfected, from whom we have received the beginning of good action. — Commentary on the Catholic Epistles
