Is Christianity hard or easy?

The almost impossibly hard thing is to hand over your whole self to Christ.  But it is far easier than what we are all trying to do instead.  For what we are trying to do is remain what we call “ourselves” – our personal happiness centered on money or pleasure or ambition – and hoping, despite this, to behave honestly, and chastely and humbly.  And that is exactly what Christ warned us you cannot do.  If I am a grass field – all the cutting will keep the grass field less but won’t produce wheat.  If I want wheat…I must be plowed up and re-sown.
