Again, from the same thought flows the other, of the identity of the uniform characteristic, at all stages of development or maturity. The mustard-seed and the tree, 'which is greater than all herbs,' have the same life in them. And the feeblest, tremulous little spark in some heart, just kindled, and scarcely capable of sustaining itself, is one with the flame leaping heaven-high, which lights up and cleanses the whole soul. So for those in advance, humility, and for those in the rear, hope. And something more than hope, for if you have the feeblest beginning of tremulous trust, you have that which only needs to be fostered to make you like Jesus Christ. Look at what follows our text: 'Add to your faith, virtue, and to virtue, knowledge,' and so on, through the whole linked series of Christian graces. They all come out of that trust which knits us to Him who is the source of them all. So you and I are responsible for bringing our faith to the highest development of which it is capable.
Alas! alas! are we not all like this very Apostle, who, in an ecstasy of trust and longing, ventured himself on the wave, and as soon as he felt the cold water creeping above his knees lost his trust, and so lost his buoyancy, and was ready to go down like a stone? He had so little faith, that he was beginning to sink; he had so much that he put out his hand--a desperate hand it was--and cried, 'Lord, save me!' And the hand came, and that steadied him, and bore him up till the water was beneath the soles of his feet again. 'Lord! I believe; help Thou my unbelief!'
