Quote from : How Far Is Heaven?: Rediscovering the Kingdom of God in the Here and Now Book

We preach grace, but we don’t always practice it. We talk about God’s mercy, but we don’t always want the people who need it most to know it or get in on it. We say we are in the redemption business, but the door to that redemption is often locked by us from the inside. We say, “Come in! All are welcome!” but “all” is often marked with an asterisk. How, I ask, can the world change – how can heaven come to earth – if we stingily protest against God for his grace to others, grace we have freely received ourselves? How can we pray “thy kingdom come,” and be resentful toward God and those he allows to enter the kingdom in his way and his timing?
