How do we know that scripture is the word of God?
How do we know that Scripture is the Word of God? How do we know that it is inspired and thus authentic and reliable and authoritative? There are a number of ways to attempt to answer this question. They are not mutually exclusive answers to the question, but are all related to some degree. Those who are born of God have the ability to distinguish between truth and error. There are degrees of discernment, gifting, and maturity involved here so we should not think that this verse is teaching that all true believers are united on all points of doctrine, but the Spirit does bear witness in the regenerate to basic fundamentals of the faith. How do I know that the Scriptures are the word of God? How do you know that honey is sweet? By tasting it. If your taste buds are dead, then no argument will prove its sweetness to you. You can hear other people talking about its taste, you can hear scientists talking about its chemical makeup, but you will not be convinced unless you taste it for yourself.
How do we know that scripture is the word of God?
Man has a deep desire for certainty, and he will even dabble in the occult in his effort to find out something for sure.
The life that is real is built on the divine certainties that are found in Jesus Christ. The world may accuse the Christian of being proud and dogmatic, but this does not keep him from saying, “I know!” In these closing verses of John’s letter we find five Christian certainties on which we can build our lives with confidence.
5 Proofs (Witnesses) of Divine Certainty for Christians
1. Jesus is God ()
John is saying that both the baptism and the cross of Jesus are essential parts of his Messiahship. He goes on to say that it was not by water only that he came, but by water and by blood. It is, then, clear that some were saying that Jesus came by water, but not by blood; in other words, that his baptism was an essential part of his Messiahship but his cross was not. This is what gives us our clue to what lies behind this passage.
2. Believers Have Eternal Life ()
When Sir James Simpson, the discoverer of chloroform, was on his deathbed, a friend asked him, “Sir, what are your speculations?”
Simpson replied: “Speculations! I have no speculations! ‘For I know whom I have believed, and am persuaded that He is able to keep that which I have committed unto Him against that day.’ ”
3. God Answers Prayer (1 John 5:14-15)
What breathing is to the physical man, prayer is to the spiritual man.
Charles Spurgeon, the famous preacher, was working hard on a message but was unable to complete it. It grew late and his wife said, “Why don’t you go to bed. I’ll wake you up early and you can finish your sermon in the morning.”
Spurgeon dozed off and in his sleep began to preach the sermon that was giving him so much trouble! His wife wrote down what he said and the next morning gave her preacher-husband the notes.
“Why, that’s exactly what I wanted to say!” exclaimed the surprised preacher. The message had been in his heart; it had simply needed expression. So with prayer: if we are abiding in Christ, the very desires of our heart are heard by God whether we voice them or not.
4. Christians do not Practice Sin ()
Then How does a Believer keep from sinning?
The mortal sin is the state of those who have listened to sin and refused to listen to God so often that they love sin and regard it as the most profitable thing in the world.
‘A child of God may sin, but his normal condition is resistance to evil.
