What is an idol? It is anything more important to you than God, anything that absorbs your heart and imagination more than God, anything you seek to give you what only God can give.
Timothy KellerWe instinctively tend to limit for whom we exert ourselves. We do it for people like us, and for people whom we like. Jesus will have none of that. By depicting a Samaritan helping a Jew, Jesus could not have found a more forceful way to say that anyone at all in need - regardless of race, politics, class, and religion - is your neighbour. Not everyone is your brother or sister in faith, but everyone is your neighbour, and you must love your neighbour.
Timothy Keller
