‘If you want to be my disciples, take up your cross and follow me’ (Jesus) was never intended to mean ‘If you want to be a Christian, do as you please and call yourself mine’. Indeed, ‘Not everyone who says to me ‘Lord, Lord’ will enter the Kingdom of Heaven, but the one who does the will of my Father who is in heaven’.
The problem with many Europeans, and many Americans, is that they think they belong to Jesus and they don’t. If they did, they would ‘keep his commandments’. Full stop.
