By faith, fill your soul with a due consideration of that provision which is laid up in Jesus Christ for this end and purpose – that all your lusts, even this very lust with which you are entangled, may be mortified. By faith, ponder on this – that though you are in no way able to get the conquest over your disorder by yourself, though you are weary of fighting and are utterly ready to faint, yet there is enough in Jesus Christ to yield relief to you (Philippians 4:13).
Let, then, your soul by faith be exercised with such thoughts and apprehensions as these:
‘I am a poor, weak creature. Unstable as water, I cannot excel. This corruption is too hard for me and is at the very door of ruining my soul, and I don’t know what to do. My soul is become as parched ground and a habitation of dragons. I have made promises and broken them. Vows and engagements have been made for nothing. Many times I have persuaded myself that I had gotten victory and been delivered, but I have been deceived. I plainly see that without some eminent support and assistance, I am lost and shall be prevailed on to an utter relinquishment of God.
But yet, though this be my state and condition, let the hands that hang down be lifted up and the weak knees be strengthened. Behold, the Lord Christ, who has all fullness of grace in His heart and all fullness of power in His hand – He is able to slay all these his enemies. There is sufficient provision in Him for my relief and assistance. He can take my drooping, dying soul and make me more than a conqueror’ (Isaiah 35:7, Isaiah 40:27-31, 2 Corinthians 12:9).
The efficacy of this consideration will be found only in the practice.
