And precisely how do you propose it should be done, that is, establishing to the satisfaction of unbelievers that the Bible is the word of God?[/QUOTE]
Thank you for an honest response and a sincere question. We are not responsible for the satisfaction of unsaved people. We do strive to get a positive result, however.
We engage in conversation, the unsaved person wants to know why you are presenting the gospel, or why you think what you are saying to him is correct for him and his family.
1} God is Holy
2] God has had 40 men write the scripture over a 1600 yr time span
3] God as the creator is the only ONE who can define right from wrong.
4] As Creator God has made known His design to man.
5] Men have sinned and died in Adam, spiritual death , followed by Physical death.
6] as part of man's rebellion he has turned from God and his Holy law.
7] God has given men over to sin Rom1-3
8 ] All men will be judged by God's Holy law, They would have to be sinless and perfect, which no descendent of Adam can be, all are guilty.
9] God sent His word in many ways and by having it written.
10] God Himself came to earth as the full final revelation...In Son. Heb1
11] he was made under the lawGal 4, to redeem them that were under the law.
12] Jesus said His word will judge men at the last day;
jn12:
46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.47 And if any man hear my words,
and believe not, I judge him not: for I came not to judge the world, but to save the world.
48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
earlier jesus said this; jn8:
43 Why do ye not understand my speech? even because ye cannot hear my word.
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
45 And because I tell you the truth, ye believe me not.
46 Which of you convinceth me of sin? And if I say the truth, why do ye not believe me?
47 He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.
Something along these lines, each conversation has it's own twists and turns, adapt which other scriptures to add or take into account. I try and leave the person with no hope outside of Jesus
Once the word is established, then you can hold out the living hope of the gospel That Jesus in His substitutionary atonement has satisfied the broken law of God and been punished as our Divine substitute.
His perfect obedience is put to the account to everyone believing, the Love of God can only be known to be In Christ. To remain outside of Christ is to remain outside of the love and under the wrath of God.
