I found this passage in Richard Sibbes’ booklet The Bruised Reed, incredibly comforting – he speaks of Christ’s merciful deposition toward us, that he will not snuff our spiritual growth, no matter how small and imperfect it is:
Let us think when we are troubled with our sins that Christ has this in charge from the father, that he shall not ‘quench the smoking flax’ . . . Satan will object, ‘You are a great sinner.’ We may answer, ‘Christ is a strong savior.’ But he will object, ‘You have no faith, no love.’ ‘Yes, a spark of faith and love.’ ‘But Christ will not regard that.’ ‘Yes, he will not quench the smoking flax.’ ‘But this is so little and weak that it will vanish and come to nought.’ ‘Nay, but Christ will cherish it, until he has brought judgment to victory.’ . . . We see here what we may look for from heaven. O beloved, it is a comfortable thing to conceive of Christ aright, to know what love, mercy and strength we have laid up for us in the breast of Christ. A good opinion of the physician, we say, is half the cure. Let us make use of this mercy in our daily combat.
