It is he alone who teaches our hands to war and our fingers to fight (Psa. 144:1). Nature, as corrupted, favours its own being, and will maintain itself against Christ's government. Nature, simply considered, cannot raise itself above itself to actions which are spiritual and of a higher order and nature. Therefore the divine power of Christ is necessary to carry us above all our own strength, especially in duties in which we meet with greater opposition; for there, not only nature will fail us, but ordinary grace, unless there is a stronger and a new supply. In taking up a burden that is weightier than ordinary, if there is not a greater proportion of strength than weight, the one who undertakes it will lie under the burden; so for every strong encounter there must be a new supply of strength, as in the case of Peter, who, when he was assaulted with a stronger temptation, being not upheld and shored up with a mightier hand, notwithstanding former strength, foully fell (Matt. 26:69-74). And being fallen, in our risings up again, it is Christ that must do the work, by (1) removing, or (2) weakening, or (3) suspending opposite hindrances; and (4) by advancing the power of his grace in us, to a further degree than we had before we fell. Therefore when we have fallen, and by falls have been bruised, let us go to Christ immediately to bind us up again.

O, let me go to You! Lord, help me when I do not feel like going to you, when I feel as if I can't make it through. I know You are the good shepherd who will not abandon a lost sheep. Search me and rescue me through this dark night.
