My people are destroyed for lack of knowledge;
because you have rejected knowledge,
I reject you from being a priest to me.
And since you have forgotten the law of your God,
I also will forget your children. – Hosea 4:6 ESV
Notice that Hosea does not say that my people are destroyed for lack of faith. Knowledge and faith are different kind of things and while they are both vital, they are different.
They said to the woman, “It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is indeed the Savior of the world.” – John 4:42 ESV
Biblical faith is a conviction based on evidence and not mere credence. Even though the statement – leap of faith – is a common expression, I am not too sure the Bible recognizes this as either evidence or knowledge-based.
but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect, – 1 Peter 3:15 ESV
I remember this verse so well and it applies here perfectly —
So faith comes from hearing, and hearing through the word of Christ. – Romans 10:17 ESV
I found this quote from another expression – blind faith —
Genuine faith derives from facts presented to the mind and from which proper and correct deductions are then drawn (John 20:30,31)…. There is no such thing as “blind” faith. Faith itself is possible only when reason recognizes the trustworthiness of the testimony which produces it. – Guy N. Woods
So I looked at the resurrection story again. Mary Magdalene saw the Lord. She immediately goes and tell the other disciples and they – disbelieved. Jesus appears to two men walking. They too returned to tell the disciples – neither believed them. So the questions have to be asked – Were these disciples justified in rejecting the report of the resurrection of Jesus because they were not eyewitnesses themselves? Was their disbelief evidence of some intellectual integrity on their part? Were they to be commended for their rejection that came from two trustworthy witnesses?
No, they were not justified in their disbelief.
Afterward he appeared to the eleven themselves as they were reclining at table, and he rebuked them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen. – Mark 16:14 ESV
Facts must be reported before they can be believed.
Read how those in Corinth responded —
And he left there and went to the house of a man named Titius Justus, a worshiper of God. His house was next door to the synagogue. Crispus, the ruler of the synagogue, believed in the Lord, together with his entire household. And many of the Corinthians hearing Paul believed and were baptized. – Acts 18:7-8 ESV
What did they hear that caused them to believe? It was the testimony given by Paul. Faith is seen as the acceptance of knowledge based upon credible testimony.
Today I have faith without sight, because of credible testimony from those who were eyewitnesses.
