A. Department of Apologetics Most readers of the Bible do not realize that there is in Christian systematic theology--besides Ecclesiology, Soteriology, Christology, Pneumatology, Bibliology, etc.--A section called apologetics. It is based on the admonition of Peter:
Be ready always to give an answer (apologia, GK.) to every man that asketh you
for a reason of the hope that is in you with meekness and fear.(1 Peter 3:15)
Whatever we conclude about the definition of "faith", it cannot go against the way Jesus, Peter, and Paul dealt with it. They all entertained reasons and evidences to show to the honest seekers. Jesus listed several in John 5; Peter appealed to many in Acts 2; John and Luke appealed to eye-witnesses to convince seekers (Luke 1:1-4, Acts 3:15, 4:20, 10:39, 13:31); and Paul engaged in "metaphysical proofs".
Knowledge of this discipline of apologetics would help clear up the confusion of this questioner. There was no advocacy of "blind faith" in the Bible.
B. Communicating God To help answer this post, one merely need to keep in mind that the Bible reveals God to be a very communicative God! From the very beginning in Genesis to the end of Revelation, God has talked with mankind! As Francis Schaeffer quipped: God is there and He is not silent!
God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken to us by His Son. (Hebrews 1:1-2)
So mankind is invited to come to a God who has revealed Himself--not to an unknown God. And as the other answerers have noted, "the more one gets to know God, the more one can have a relaxed "trusting relationship" with Him. That is, a life of "faith." Much of the O.T. contains references to the faithful and supernatural acts of God, a rehearsal of the character of Jehovah, in attempts to encourage continual trust (faith) in Him.
So again, there is no such thing as "blind faith."
C. Expository Bible Study A third aspect that the questioner must be aware of is the fact that Topical Bible Study is not the best way to study verses. It is okay to use a Concordance to find references for particular words. But to learn what they mean, expository research is the best way to go about it.
To list a couple of verses that have the same word in them can lead to confusion because they do not take into account the context of the verses. Verses were written at different time periods, to different people, on different occasions, for different purposes. Just reading a group of verses with the same word, leads to confusion, misunderstanding, etc.
If this expository research had been done, the second half of this posted question would have been unnecessary. There would have been no misunderstanding concerning the meaning of "faith." There would have been no entertaining of the possibility of any such thing as "blind faith."
- For example, take the verse of Hebrews 11:1 which was quoted. If the next verse were also quoted, it would have helped understand faith:
Through faith we understand that the worlds were framed by the Word of God, so that things which were seen were not made of things which do appear. (Hebrews 11:3)
Paul also appealed to the Cosmological Proof for the existence of God in Romans 1, and Acts 17. The chapter context of Hebrews 11 also reveals that the following list of men of faith was given as evidence to the Hebrews that they also should believe in God.
As far as the other verse, We walk by faith and not by sight (2 Corinthians 5:7) has the context of "dying and going to heaven to be with Jesus." (Both verses before it and after it.) In other words, Paul was assuring the church that we will be with Christ in heaven, not because of Naturalistic, materialistic, secular philosophies (of things seen), but rather because of our living a life of trust (faith) in God., an intangible, unseen, merciful reliance upon Jesus's grace.
The third verse about "not seeing" calls those who were not present in the first century "blessed" if they too believe the eye-witnesses testimony (the preaching of the Gospel). {That includes us!} But notice the context. The very next verse stated:
And many other signs truly did Jesus in the presence of His disciples, which are not written in this book. But these are written so that you might believe that Jesus is the Christ, the Son of God... (John 20:30-31)
So an expository research, instead of a topical one, would have made this query unnecessary.
D. Informed Faith Progress Christian faith is a religion based on "substance" and "evidence," given by a communicating God, so that a person can confidently trust in God (with an informed faith) through the walk of life and Christian discipleship, onward into eternal life.
To better understand this, perhaps we should discern the different stages in "coming to faithful living." (1) Convincing, (2) Converting, (3) Conversing. Or (1) Pre-evangelism, (2) Evangelism, (3) Post-evangelism: discipleship. Or still, (1) Pulling weeds, (2) Planting seeds, (3) Harvesting deeds.
Each step brings a person to faith, and then increases his faith, and then pleases God with a faithful relationship (with a trusting God, just like the patriarchs had, Hebrews 11.)
