Saw this somewhere and decided to take the challenge.
Jesus. Christianity is based on Jesus, not a church or a prescribed set of beliefs.
Love. Christianity is based on love, loving God, loving others (especially those we do not understand), and loving ourselves (in a healthy, non-arrogant sort of way, since he loves us).
Life. Christianity is woven into our lifestyle, not something tacked on, not something to sign off on, not something that happens on a special day or in a special place.
Grace. Christianity is based on grace, grace that always gives us hope, even in our darkest hours and deepest failures, and is extended to others.
