Part of the problem about authenticity is that virtues aren't the only things that are habit forming: the more someone behaves in a way that is damaging to self or to others, the more "natural" it will both seem and actually be. Spontaneity, left to itself, can begin by excusing bad behavior and end by congratulating vice.

I came to Paul at quite an early age, having already studied Plato and Aristotle; and I found Paul easily their intellectual equal, though he was handling these amazing questions about God, Jesus, Israel, faith and so on. He continues to be an amazingly stimulating thinker, especially when we try to understand the flow of thought in letter after letter rather than just combing him for a few verses on 'our favourite topics', which, sadly, some Christian teachers do just as some journalists and broadcasters do!

What you do in the present—by painting, preaching, singing, sewing, praying, teaching, building hospitals, digging wells, campaigning for justice, writing poems, caring for the needy, loving your neighbor as yourself—will last into God’s future. These activities are not simply ways of making the present life a little less beastly, a little more bearable, until the day when we leave it behind altogether. They are part of what we may call building for God’s kingdom.

Hope comes as a surprise, at several levels at once.

Worship is humble and glad, worship forgets itself in remembering God; worship celebrates the truth as God's truth, not its own.

To pray 'your kingdom come' at Jesus' bidding meant to align oneself with his kingdom movement.

At the heart of Christian ethic is humility; at the heart of its parodies, pride. Different roads with different destinations, and the destinations color the character of those who travel by them.
