Romans 12:9
9Let love be without hypocrisy. Abhor that which is evil. Cling to that which is good.
Love without a mask. Abhor evil; hold fast to good. Wesley: having spoken of faith and its fruit, he comes now to love—both inwardly and outwardly, whatever ill-will or danger may follow. True love is faith wearing clothes, not a sentiment we perform for the room.
Grace enables a sincerity. The command is not a slogan; it is the Spirit’s call to a people who must still refuse play-acting and cling to that which is good. In love that can be faked is exactly what Paul rules out.
Calvin: all disguises are to be cast aside; love is no other than that which is free from dissimulation. Evil here is the malice that injures; good is the kindness that helps. The living sacrifice of 12:1 now has a manner.
True love is the bond of a people God has made. The indicative of mercy becomes the church’s ordinary life. We do not manufacture this love from native warmth; we receive it as the fruit of a heart already claimed.
