Let us consider 
the danger we expose our selves to by not living answerably to our 
Religion. And this, I hope, may prevail upon such as are not moved by 
the former considerations. Hypocrites are instanced in Scripture, as a 
sort of sinners that shall have the sharpest torments and the fiercest 
damnation. When our Saviour would set forth the great severity of the 
Lord towards the evil servant he expresseth it thus, he shall cut him 
asunder and appoint him his portion with Hypocrites. So that the 
punishment of Hypocrites seems to be made in the measure and standard of
 the highest punishment. Thou professest to believe in Christ and to 
hope in him for salvation, but in the mean time thou livest a wicked and
 unholy life, thou dost not believe but presume on him, and wilt find at
 the great day that this thy confidence will be thy confusion, and he 
whom thou hopest will be thy Advocate and Saviour will prove thy Accuser
 and thy Judge. What our Saviour says to the Jews, 'There is one that 
accuseth you, even Moses in whom ye trust,' may very well be applied to 
false Christians, there is one that accuseth you and will condemn you, 
even Jesus in whom ye trust.
The profession of 
Christianity and mens having the name of Christ named upon them will be 
so, far from securing them from Hell, that it will sink them the deeper 
into it. Many are apt to pity the poor Heathens who never heard of the 
name of Christ, and sadly to condole their case, but as our Saviour said
 upon another occasion, 'Weep not for them, weep for yourselves.' There 
is no such miserable person in the world as a degenerate Christian, 
because he falls into the greatest misery from the greatest advantages 
and opportunities of being happy. Dost thou lament the condition of 
Socrates, and Cato, and Aristides, and doubt what shall become of them 
at the day of Judgment? and canst thou who art an impious and prophane 
Christian, think that thou shalt escape the damnation of Hell?
Dost
 thou believe that the moral Heathen shall be cast out? and canst thou 
who hast led a wicked life under the profession of Christianity have the
 impudence to hope that thou shalt sit down with Abraham, Isaac and 
Jacob in the Kingdom of God? No: those sins which are committed by 
Christians under the enjoyment of the Gospel are of deeper dye and 
cloathed with blacker aggravations than the sins of Heathens are capable
 of. A Pagan may live without God in the World, and be unjust towards 
men, at a cheaper rate and upon easier terms than thou who art a 
Christian. Better had it been thou hadst never known one syllable of the
 Gospel, never heard of the name of Christ, than that having taken it 
upon thee thou shouldest not depart from iniquity. Happy had it been for
 thee, that thou hadst been born a Jew, or a Turk, or a poor Indian, 
rather than that being bred among Christians, and professing thy self of
 that number, thou shouldst lead a vicious and unholy life.
I
 have insisted the longer upon these arguments, that I might, if 
possible, awaken men to a serious consideration of their lives, and 
persuade them to a real reformation of them; that I may oblige all those
 who call themselves Christians to live up to the essential and 
fundamental Laws of our Religion; to love God, and to love our 
Neighbour; to do to every man as we would have him to do to us; to 
mortify our lusts, and subdue our passions, and sincerely endeavour to 
grow in every grace and virtue, and to abound in all the fruits of, 
righteousness which are by Jesus Christ to the praise and glory of God.
This
 indeed would become our profession and be honourable to our Religion, 
and would remove one of the greatest obstacles to the progress of the 
Gospel. For how can we expect that the Doctrine of God our Saviour 
should gain any considerable ground in the world; so long as by the 
unworthy lives of so many Christians 'tis represented to the world at so
 great disadvantage? If ever we would have Christian Religion 
effectually recommended, it must be by the holy and unblameable lives of
 those who make profession of it. Then indeed it would look with so 
amiable a countenance as to invite many to it and carry so much majesty 
and authority in it as to command reverence from its greatest enemies, 
and make men to acknowledge that God is in us of a truth, and to glorify
 our Father which is in Heaven.
The good God grant that as
 we have taken upon us the profession of Christianity, so we may be 
careful so to live that we may adorn the doctrine of God our Saviour in 
all things; that the grace of God which bringeth salvation may teach us 
to deny ungodliness and worldly lusts, and to live soberly, righteously 
and godly in this present world; looking for that blessed hope, and the 
glorious appearing of the great God and our Saviour Jesus Christ; To 
whom with the Father and the Holy Ghost, &c.
