(4.) As we should strive for, and by faith, so we should strive by prayer, by fervent and effectual prayer. (Romans 15:30) O the swarms of our prayerless professors! What do they think of themselves? Surely the gate of heaven was heretofore as wide as in these our days; but what striving by prayer was there then among Christians for the thing that gives admittance into this kingdom, over [what] there is in these latter days!
(5.) We should also strive by mortifying our members that are upon the earth. "I therefore so run," said Paul, "not as uncertainly; so fight I, not as one that beateth the air; but I keep under my body, and bring it into subjection, lest that by any means, when I have preached the gospel to others, I myself should be a cast-away." (1 Cor 9:26,27) But all this is spoken principally to professors; so I would be understood.
[Why should we strive?]
III. I come now to the third question, namely, But why should we strive? Answer—
1. Because the thing for which you are here exhorted to strive, it is worth the striving for; it is for not less than for a whole heaven, and an eternity of felicity there. How will men that have before them a little honour, a little profit, a little pleasure, strive? I say again, how will they strive for this? Now they do it for a corruptible crown, but we an incorruptible. Methinks this word heaven, and this eternal life, ought verily to make us strive, for what is there again either in heaven or earth like them to provoke a man to strive?
2. Strive, because otherwise the devil and hell will assuredly have thee. He goes about like a roaring lion, seeking whom he may devour. (1 Peter 5:8) These fallen angels, they are always watchful, diligent, unwearied; they are also mighty, subtle, and malicious, seeking nothing more than the damnation of thy soul. O thou that art like the artless dove, strive!
3. Strive, because every lust strives and wars against thy soul. "The flesh lusteth against the Spirit." (Gal 5:17) "Dearly beloved, I beseech you," said Peter, "as strangers and pilgrims, abstain from fleshly lusts, which war against the soul." (1 Peter 2:11) It is a rare thing to see or find out a Christian that indeed can bridle his lusts; but no strange thing to see such professors that are "not only bridled, but saddled too," yea, and ridden from lust to sin, from one vanity to another, by the very devil himself, and the corruptions of their hearts.
4. Strive, because thou hast a whole world against thee. The world hateth thee if thou be a Christian; the men of the world hate thee; the things of the world are snares for thee, even thy bed and table, thy wife and husband, yea, thy most lawful enjoyments have that in them that will certainly sink thy soul to hell, if thou dost not strive against the snares that are in them. (Rom 11:9)
The world will seek to keep thee out of heaven with mocks, flouts, taunts, threatenings, jails, gibbets, halters, burnings, and a thousand deaths; therefore strive! Again, if it cannot overcome thee with these, it will flatter, promise, allure, entice, entreat, and use a thousand tricks on this hand to destroy thee; and observe, many that have been stout against the threats of the world, have yet been overcome with the bewitching flatteries of the same. 5
There ever was enmity betwixt the devil and the church, and betwixt his seed and her seed too; Michael and his angels, and the dragon and his angels, these make war continually. (Gen 3, Rev 12) There hath been great desires and endeavours among men to reconcile these two in one, to wit, the seed of the serpent and the seed of the woman, but it could never yet be accomplished. The world says, they will never come over to us; and we again say, by God's grace, we will never come over to them. But the business hath not ended in words; both they and we have also added our endeavours to make each other submit, but endeavours have proved ineffectual too. They, for their part, have devised all manner of cruel torments to make us submit, as slaying with the sword, stoning, sawing asunder, flames, wild beasts, banishments, hunger, and a thousand miseries. We again, on the other side, have laboured by prayers and tears, by patience and long-suffering, by gentleness and love, by sound doctrine and faithful witness-bearing against their enormities, to bring them over to us; but yet the enmity remains; so that they must conquer us, or we must conquer them. One side must be overcome; but the weapons of our warfare are not carnal, but mighty through God.
