"If we would come rightly prepared to the sacrament [of the Lord's Supper] we must come with humble hearts. We see Christ humbling himself to the death; and will a humble Christ ever be received into a proud heart? ... A sight of God's glory, and a sight of sin, may humble us. Was Christ humble, who was all purity? And are we proud, who are all leprosy? Oh, let us come with a sense of our own vileness. How humble should he be who is to receive an alms of free grace! 

Jesus Christ is a 'lily of the valleys' (Song of Sol. 2:1), not of the mountains. Humility was never a loser. The emptier the vessel is, and the lower it is let down into the well, the more water it draws up; so the more the soul is emptied of itself, and the lower it is let down by humility, the more it fetches out of the well of salvation. God will come into a humble heart to revive it (Isa. 57:15). That is no part of Christ's temple which is not build with a low roof.

(The Lord's Supper, Thomas Watson, 50)
