If from one burning lamp someone lights another, then another from that one, and so on in succession, he has light continuously. In the same way, through the Apostles ordaining their successors, and these successors ordaining others, and so on, the grace of the Holy Spirit is handed down through all generations and enlightens all who obey their spiritual shepherds and teachers.

Given that we desire long life, should we not take eternal life into account? If we long for a kingdom which, however enduring, has an end, and glory and joy which, great as they are, will fade, and wealth that will perish with this present life, and we labour for the sake of such things; ought we not to seek the kingdom, glory, joy and riches which, as well as being all-surpassing, are unfading and endless, and ought we not to endure a little constraint in order to inherit it?

"I am afraid that God has sent these men to lay waste the world".

They either attach themselves to God's will, which results in their continuous progress, improvement and advancement, or they oppose God's will, are justly subjected to what He permits, and sink wretchedly from bad to worse.

... whenever Christ, the Bridegroom of pure souls, is mystically united with each soul, He gives the Father occasion to rejoice over this as at a wedding. It is Christ Himself Who says, 'Joy shall be in heaven over one sinner who repents' (Lk. 15:7). For joy, according to the Apostle, is the fruit of the Holy Spirit (Gal. 5:22), Who through conversion brings back to Christ those living in repentance, and reunites them with Him. And this joy embraces both those in heaven and godly men on earth. That is why there is joy in heaven over one repentant sinner.

'Now we are the sons of God'. This is the starting point of adoption. However, 'it does not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is' (I Jn. 3:2). This is the perfection of adoption of sons and renewal which God bestowed on us in Christ, and of which John says in his Gospel that, 'Christ gave power to become the sons of God, even to them that believe on His name: which were born, not of blood, nor of the will of the flesh nor of the will of man, but of God' (Jn. 1:12-13).

... we can see both that love for God is begotten from the virtues and that virtues are born of love. For this reason the Lord said at one point in the Gospels, 'He who has My commandments and keeps them is the one who loves Me' (Jn. 14:21), and at another point, 'He who loves Me will keep My commandments' (cf. Jn. 14:23).
