We are continuing in this post by examining some questions posed by inquisitive atheists provoked by their unbelief. One question you might hear is, “Why does God need your defense?” The short answer is, “He doesn't.” This question is either a crafty intent designed to place you on the defensive or a misunderstanding of Christian apologetics. Nowhere in scripture is the Christian instructed to defend the existence of God. On the contrary, God makes it clear He needs no defending.
Romans 1:19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. (ESV)
Of course, that does not mean they will not offer an excuse or demand you show them evidence, however, that is beyond your responsibility, creation itself leaves them without excuse. However, the Christian does have the responsibility to answer for his faith and defend his doctrine.
1 Peter 3:15 But sanctify the Lord God in your hearts, and be ready always to give an answer to every man who asketh you a reason for the hope that is in you, with meekness and fear.
"To give an answer" (ἀπολογίαν apologian.) Anyone has a right respectfully to ask another on what grounds he regards his religion as true; for every man has a common interest in religion, and in knowing what is the truth on the subject. If any man, therefore, asks us candidly and respectfully by what reasons we have been led to embrace the gospel, and on what grounds we, regard it as true, we are under obligation to state those grounds in the best manner that we are able. We should regard it not as an impertinent intrusion into our private affairs, but as an opportunity of doing good to others, and to honor the Master whom we serve. Nay, we should hold ourselves in readiness to state the grounds of our faith and hope, whatever maybe the motive of the inquirer, and in whatever manner the request may be made. - Albert Barnes
Jude 1:3 Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints.
The system of religion revealed in the gospel. It is called "faith," because that is the cardinal virtue in the system, and because all depends on that. The rule here will require that we should contend in this manner for all "truth." - Albert Barnes
In one case we are explaining why we believe the Gospel and in the other we are defending what we believe about the Gospel. We should be able to do both from the scriptures.
Another question you might hear is, "If the Bible is the ultimate moral guide, why do so many Christians disagree on what it says." These are not questions for serious inquiry, you might as well ask why people in general disagree about anything. If politics are real, why do people disagree about politics? If climate is real, why do people disagree on climate change. Some say people are the ultimate moral guide, why do so many people differ in their morality? The fact people disagree has nothing to do with Biblical truth, it has everything to do with people. The question itself misses the point completely, the Bible is not intended to be a moral guide for anybody, it is the history of man's redemption from the fall and a means to his Salvation.

Atheist will sometimes inquire, "Why is God so hard to find?" This question is particularly interesting because it comes from an atheist who professes to have onces been a minister of the Gospel. It reveals he never understood the Gospel, regardless of what he claims to have been.
God is not hiding Himself, he has very acutely described how He has chosen to reveal himself. The atheist have their own idea's of how God should reveal himself, but God being God has the right to reveal himself in whatever manner he has chosen. The atheist perhaps can say God has not revealed himself in the manner they like, but they cannot say He has not done so. The verse in Romans we have already mentioned is just simply ignored.
Romans 1:19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. (ESV)
John describes it this way: John 1:1, In the beginning was the Word, and the Word was with God, and the Word was God.
2, The same was in the beginning with God.
3, All things were made through him; and without him was not anything made that hath been made.
4, In him was life; and the life was the light of men.
5, And the light shineth in the darkness; and the darkness apprehended it not.
6, There came a man, sent from God, whose name was John.
7, The same came for witness, that he might bear witness of the light, that all might believe through him.
8, He was not the light, but came that he might bear witness of the light.
9, There was the true light, even the light which lighteth every man, coming into the world.
10, He was in the world, and the world was made through him, and the world knew him not.
11, He came unto his own, and they that were his own received him not.
12, But as many as received him, to them gave he the right to become children of God, even to them that believe on his name:
13, who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. (ASV)
In his further pondering, the atheist suggested if God really wanted to make himself known, he would. However, the atheist ignores the fact God already has. John 1:14, And the Word became flesh, and dwelt among us (and we beheld his glory, glory as of the only begotten from the Father), full of grace and truth.
15, John beareth witness of him, and crieth, saying, This was he of whom I said, He that cometh after me is become before me: for he was before me. (ASV)
What the atheist is doing is described in Paul in the book of Acts. Acts 17: 27, That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us: John Gill explains: That they should seek the Lord,.... Or "God", as the Alexandrian copy and others, and the Vulgate Latin, Syriac, and Ethiopic versions read; their Creator, and kind Benefactor, and who has appointed their time of life, and their habitations for them; and this should engage them to seek to know him, who has done all this for them, and to fear and serve him, and to glorify his name:
The atheist speak of God as if he is one like unto ourselves, they want Him to show up and demonstrate himself to them. If He is real, surely He would show himself. But God is not like us, no man has ever seen God, nor ever will. Who and what He is in relation to us has been shown to us in the person of Jesus Christ.
John 1:18 ESV
No one has ever seen God; the only God, who is at the Father's side, he has made him known.
1 Timothy 6:16 ESV
Who alone has immortality, who dwells in unapproachable light, whom no one has ever seen or can see. To him be honor and eternal dominion. Amen.
Co. 4:4 ASV In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.
Colossians 1:15 ESV
He [Jesus Christ] is the image of the invisible God, the firstborn of all creation.
Romans 1:20 ESV
For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
He attributes and eternal power and divine nature is clearly seen in His creation. The atheist wants to see the unseeable, to know the unknowable, to conceive the inconceivable. So he challenges your faith in hopes to get you to do the same. But Hebrews 11:3 ESV By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible. This is simply the nature of things between a believer and non-believer. Our responsibility is to articulate the Gospel and demonstrate why it is we believe and hope God will grant them repentance and faith to see the invisible
Hebrews 11: 24–27 By faith Moses, when he was grown up, refused to be called the son of Pharaoh’s daughter, 25 choosing rather to be mistreated with the people of God than to enjoy the fleeting pleasures of sin. 26 He considered the reproach of Christ greater wealth than the treasures of Egypt, for he was looking to the reward. 27 By faith he left Egypt, not being afraid of the anger of the king, for he endured as seeing him who is invisible.
May God bless,
