Nay, 20.  We would remember for our encouragement and confidence, that in carrying on of this work lieth the satisfaction of the soul, and the pleasure of the Lord that must prosper in his hand, and thus he seeth his seed, and hath of the travail of his soul, and is satisfied.

These particulars, rightly considered, will discover unto us, what a noble ground for sanctification is in Christ laid down for believers, which they may, and must by faith grip to, that they may grow in grace, and grow up in Christ, and perfect holiness; and what a wonderful contrivance of grace this is, wherein all things are made so sure for believers, Christ becoming all things to them, and paving a royal and sure way for them; sure for them, and glorious to himself!

As to the second particular, that is, how believers are to carry in this matter, or how they are to make use of Christ, and of those grounds of sanctification in Christ, which we have mentioned: 

First, There are some things which they should beware of, and guard against; as,

1.  They should beware of an heartless despondency, and giving way to discouragement, and hearkening to the language of unbelief, or to the suggestion of Satan, whereby he will labour to persuade them of the impossibility of getting the work of sanctification throughed, or any progress made therein to purpose.  Satan and a deceitful heart can soon muster up many difficulties, and allege that there are many lions, many insuperable difficulties in the way, to discourage them from venturing forward; and if Satan prevail here, he hath gained a great point.  Therefore the believer should keep up his head in hope, and beware of multiplying discouragements to himself, or of concluding the matter impossible; for then shall he neither have heart nor hand for the work, but sit down and wring his hands as overcome with discouragement and despondency of spirit.

2.  They should beware of wilfully rejecting their own mercies, and forbearing to make use of the grounds of hope, of strength and progress in the matter of sanctification, which Christ hath allowed them to make use of.  There is such an evil among God’s children, that they scar at that which Christ out of great love hath provided for them, and dare not with confidence make use of, nor apply to themselves the great and comfortable promises, to the end they might be encouraged; they will not take their allowance, as thinking themselves unworthy; and that it would be presumption in them to challenge a right to such great things; and they think it commendable humility in them, to stand a-back, and so wilfully refuse the advantages and helps, that make so much for their growth in grace.

3.  They should beware of a careless neglect of the means appointed for advancing in holiness; for, though the means do not work the effect, yet it is by the means that God hath chosen to work the work of sanctification.  Here that is to be seen, “that the hand of the diligent maketh rich; and the field of the slothful is soon grown over with thorns and nettles; so that poverty cometh as one that travaileth, and want as an armed man,” Prov. xxiv. 30.  It is a sinful tempting of God, to think to be sanctified another way than God hath in his deep wisdom condescended upon.
