If we believe not with faith divine and supernatural, we believe not at all.

All spiritual acts well-pleasing unto God, as faith, repentance, obedience, are supernatural; flesh and blood revealeth not these things.

It must be observed, that the best of men, the most holy and spiritually minded, may have, nay, ought to have, their thoughts of spiritual things excited, multiplied, and confirmed, by the preaching of the word.

To believe that He will preserve us is, indeed, a means of preservation. God will certainly preserve us, and make a way of escape for us out of the temptation, should we fall. We are to pray for what God has already promised. Our requests are to be regulated by His promises and commands. Faith embraces the promises and so finds relief.

...but let it suffice us to know that it became God, who is the supreme Ruler, Governor and Judge of all that sin should be punished with death in the sinner or his surety; and therefore if God would bring many sons to glory, the Captain of their salvation must undergo sufferings and death, to make satisfaction for them.

Without a sincere and diligent effort in every area of obedience, there will be no sucessful mortification of any one besetting sin.

Your state is not at all to be measured by the opposition that sin makes to you, but by the opposition you make to it.
