Faith - is from the Greek word pistis and it means to believe.
Believing can be defined as having confidence and trust in knowledge received to the end that you act upon it. By this definition believing is dependent upon knowledge or information. If you have been given knowledge of what a certain stock is going to do in the stock market and you have confidence and trust in the source of that knowledge to the end that you buy the stock you could say that you believed the person who told you about the stock. If, on the other hand you did not have confidence and trust in the person who told you about the stock and therefore do not buy the stock you did not believe him as evidenced by the fact that you took no action upon the knowledge given you.
In Hebrews Chapter 11 a "hall of fame" of believers is cited. Men and women who, although they could not see God, believed Him by acting upon knowledge or information given them from God.
Things hoped for - Hope is the anticipation of something to come in the future.
Hope is the goal. Hope is that "finish line" we focus on when we do the tasks we have to do to get there. In Hebrews Chapter 11 believers acted upon information they had received from God in anticipation of something to come in the future. While they did not attain the promised hope during their lifetime, they acted on the Word of God believing that God was faithful to His Word.
Now believing is the substance of things hoped for, . . .
Substance is the Greek word hupostasis which means foundation or confidence upon which something rests.
Believing is the foundation or concrete action upon which our hope rests. We anticipate that which is still future and move in that direction with concrete action upon the knowledge that we have of God and His word.
the evidence of things not seen.
Believing is the evidence or proof of that
which we have not yet seen. We have not seen God who supplies the
information upon which we act. We have not yet obtained the goal
of Christ's return or received our new spiritual body [Philippians
3:21]. Those believers who have
died have not yet attained the resurrection of the dead. Yet our
action upon God's Word is the proof, the evidence, the foundation that
demonstrates to the world that God is and that He is a rewarder of them
that diligently seek Him. Our believing action on the knowledge
of God is evidence that Christ is going to return and we will be gathered
together to meet him in the air. It is the proof that we are moving
toward the goal.
We received the hope of righteousness by believing
God's Word. When we believed what God said in Romans
10:9-10 and acted upon God's promise we
received holy spirit and that hope of righteousness that so many others
worked toward in the Old Testament but were unable to attain.
We attained access to the grace of God through the believing action
of His son, Jesus Christ, and we believe God's Word by acting upon
it as we look forward to the glory of God that He has promised us in the
future at the return of Jesus Christ.
Our believing action upon God's Word is the
foundation, the evidence, the proof, upon which we are grounded and settled
as we focus on the goal of the hope we anticipate.
Believing is work. Acting upon the Word
of God out of love is hard work. It is the substance, the foundation,
the concrete action of our walk that we do as we patiently look toward
the hope of Christ's return.
Believing and love are the actions that protect
our heart. Hope is the helmet that protects our head. We work
from the heart and keep our head focused on the goal.
