Christianity is a necessity, and yet most available versions of Christianity present Life as an obstacle course of rules and regulations: do and don'ts.
Yet we are so weak and labile that such a recipe is overwhelming in its difficulty. Most of us would have no motivation or energy left-over after satisfying the requirements...
We yearn to be free, and creative, and face Life with as care-free an attitude as possible - we want to live from our-selves not to somebody else's blueprint.
The Good news is that Christianity, but only Christianity, enables exactly this; because the gift of repentance allows us to do our best, fail, and start again - without limit.
Instead of being paralysed (or hardened) by impossible laws, we are enabled to face Life as an adventure, secure in the infinite power of repentance.
Indeed, wasn't this the Main point of Christianity?
