Our sin must be extremely horrible. Nothing reveals the gravity of sin like the cross. For ultimately what sent Christ there was neither the greed of Judas, nor the envy of the priests, not the vacillating cowardice of Pilate, but our own greed, envy, cowardice, and other sins, and Christ’s resolve in love and mercy to bear their judgment and so put them away.

It is impossible for us to face Christ’s cross with integrity and not feel ashamed of ourselves. Apathy, selfishness, and complacency blossom everywhere in the world except at the cross. There these noxious weeds shrivel and die. There they are seen for the tatty, poisonous things they are. For if there was no way by which the righteous God could righteously forgive our unrighteousness, except that he should bear it himself in Christ, it must be serious indeed…  –from  John Stott, The Cross of Christ
