3. He should consider, that, as it is a very unseemly thing for him to be a slave to that old tyrant, and to yield his members as so many servants to iniquity, so it is dangerous and deadly. His life lieth at the stake; either he must get it mortified, killed, and subdued, or it will kill him; his life will go for its life; if this enemy escape, he is a gone man. The consideration of this should cause the believer to act here in earnestness and seriousness, with care and diligence, and set about this work of mortification with labour and pains. 4. Much more must it be against all reason and Christianity, for the believer to be making "provision for the flesh, to fulfil the lusts thereof," Rom. xiii. 14. To be strengthening the hands of, and laying provision to this enemy, which is set and sworn against us, can stand with no reason. And here is much of the Christian's prudence and spiritual wisdom required, to discern what may make for fostering of this or that corruption, or member of the body of sin and death, and to withdraw that, as we will labour to take away provision of any kind from an enemy that is coming against us. Paul acted herein as a wise gamester and combatant, when he kept under his body, and brought it into subjection, 1 Cor. ix. 27. It were but to mock God, and to preach forth our own folly, to be looking to Christ for help against such an enemy, and, in the meantime, to be underhand strengthening the hands of the enemy; this would be double dealing, and treachery against ourselves.
