For Christians see that with Jesus human and divine nature began to be woven together, so that by fellowship with divinity human nature might become divine, not only in Jesus, but also in all those who believe and go on to undertake the life which Jesus taught, the life which leads everyone who lives according to Jesus’ commandments to friendship with God and fellowship with Jesus.

– Origen of Alexandria, Contra Celsum
(Henry Chadwick, trans.)

He has by his own action given us everything that is necessary for living the truly good life, in allowing us to know the one who has called us to him, through his own glorious goodness. It is through him that God’s greatest and most precious promises have become available to us men, making it possible for you to escape the inevitable disintegration that lust produces in the world and to share in God’s essential nature.

For this very reason you must do your utmost from your side, and see that your faith carries with it real goodness of life. Your goodness must be accompanied by knowledge, your knowledge by self-control, your self-control by the ability to endure. Your endurance too must always be accompanied by devotion to God; that in turn must have in it the quality of brotherliness, and your brotherliness must lead on to Christian love.

If you have these qualities existing and growing in you then it means that knowing our Lord Jesus Christ has not made your lives either complacent or unproductive. The man whose life fails to exhibit these qualities is short-sighted—he can no longer see the reason why he was cleansed from his former sins.

Set your minds, then, on endorsing by your conduct the fact that God has called and chosen you. If you go along the lines I have indicated above, there is no reason why you should stumble, and if you have lived the sort of life I have recommended God will open wide to you the gates of the eternal kingdom of our Lord and Saviour Jesus Christ.

– 2 Peter 1:3-11 (Phillips)
