Speaking Divine Truth

I am blessed and encouraged by Christians who are intelligent, gracious apologists who take an unapologetic stand on the truth of God's word.  Exploring perspectives and beliefs personally can be beneficial, and God can use these interactions to draw people to Himself.  As we are led by the Holy Spirit, we are Christ's ambassadors to bring the message of reconciliation of sinners to God through the Gospel.  It is important we emphasise the Gospel is not our opinion or view in a sea of options, but Jesus Christ is the exclusive way to eternal life, the Truth in a world of error.  Spurgeon made this point very well in a sermon titled "Gospel Missions," that the divine revelation aspect of our Christian faith can be neglected:

"...I conceive that a great mistake has been made in not affirming the divinity of our mission, and standing fast by the truth, as being a revelation, not to be proved by men, but to be believed; always holding out this:  "He that believeth and is baptized shall be saved; he that believeth not shall be damned."  I am often grieved when I read of our missionaries holding disputes with the Brahmins; and it is somethings said that the missionary has beaten the Brahmin because he kept his temper, and so the gospel had gained great honour by the dispute.  I take it, that the gospel was lowered by the controversy.  I think the missionary should say:  "I am come to tell you something which the one God of heaven and earth hath said, and I tell you, before I announce it, that if you believe it you shall be saved, and if not you shall be damned.  I am come to tell you that Jesus Christ, the Son of God, became flesh to die for poor unworthy man, that through his mediation, and death, and suffering the people of God might be delivered.  Now, if you will listen to me, you shall hear the word of God: if you do not, I shake the dust off my feet against you, and go somewhere else.

Look at the history of every imposture; it shows that the claim of authority insures a great degree of progress.  How did Mahommed come to have so strong a religion in his time?  He was all alone, and he went into the market-place and said, "I have received a revelation from heaven."  It was a lie, but he persuaded men to believe it.  He said, "I have a revelation from heaven."  People looked at his face; they saw that he looked upon them earnestly as believing what he said, and some five or six of them joined him.  Did he prove what he said?  Not he.  "You must," he said, "believe what I say, or there is no Paradise for you."  There is a power in that kind of thing; and wherever he went his statement was believed, not on the ground of his reasoning, but on his authority, which he declared to be from Allah; and, in a century after he first proclaimed his imposture, a thousand sabres had flashed from a thousand sheathes, and his word had been proclaimed through Africa, Turkey, Asia, and even in Spain.  The man proclaimed authority,--he claimed divinity; therefore he had power.  Take, again, the increase of Mormonism.  What has been its strength?  Simply this,--the assertion of power from heaven.  That claim is made, and the people believe it, and now they have missionaries in almost every country of the habitable globe, and the book of Mormon is translated into many languages.  Though there never could be a delusion more transparent, or a counterfeit less skilful and more lying upon the very surface, yet this simple pretension to power has been the means of carrying power with it.

Now, my brethren, we have power; we are God's ministers; we preach God's truth; the great judge of heaven and earth has told us the truth, and what have we to do to dispute with worms of the dust?  Why should we tremble and fear them?  Let us stand out and say:  "We are the servants of the living God; we tell unto you what God has told us, and we warn you, if you reject our testimony, it shall be better for Tyre and Sidon in the day of judgment than for you."  If the people cast that away, we have done our work.  We have nothing to do with making them believe; ours is to testify of Christ everywhere, to preach and proclaim the gospel to all men."
