Crosses, planted by the hand of a wise providence, meet us at every step. And we are not at liberty to avoid them. We cannot avoid them without turning aside from God himself. And accordingly, in the spirit of a heart crucified, we must always stoop to the burden, which they impose upon us and must take them on our shoulders, and must bear them as humbly, as willingly, and as rejoicingly as Christ bore his. And happy is the soul, that knows from his own inward experience, that a sanctified Cross is a storehouse of spiritual blessings.
Inward crucifixion, when carried, as it always ought to be, to its full extent, is the result of strong faith. It is hardly necessary to make remarks in support of this proposition. Who would relinquish the world, with the attractions the world holds out, be they more or less, if he had not faith in something better than the world? Who, that is destitute of faith, can find in himself or elsewhere the power which is requisite to keep the various propensities and passions in their place, and in their right action moment by moment? Where will the man, that is without faith, find resources to sustain himself, against the trial of heavy temptations, without a fear or a murmur arising from the workings of a selfish nature? Who can walk in God’s way and will, deprived by his special providence of all inward consolations, without faith? How can a man have his soul so fixed upon God as not to look with a self-interested complacency even on his spiritual gifts and graces, without the supports of a strong faith? We need not delay upon this matter. It is exceedingly obvious, we think, and the concession is confirmed by the experience and testimony of all devout Christians, that without faith the results, which are involved in inward crucifixion, cannot be realized.
