First, the bible says that faith is a susbtance.

[Hebrews 11:1-3 KJV] Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report. Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.

The world says it’s simply a noun: complete trust or confidence in someone or something. “this restores one’s faith in politicians”.

Anyone putting faith in politicians is putting their faith in man.  That’s their first mistake. 

Its much more…

The bible says it’s the key to eternal life, for one. 

[Ephesians 2:8 KJV] For by grace are ye saved through faith;

If it’s that important, what you put your faith in must be of supreme importance. 

The bible says put your faith in Jesus and you will be justified and have peace with God through our Lord Jesus Christ.

[Romans 5:1-2 KJV] Therefore being justified by faith, we have peace with God through our Lord Jesus Christ: By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.

God is a Spirit, not a religion.  Yes, the bible is a religious book, but it is also a spiritual book.  God is the Spirit of Truth.  God’s Word has multiple functions that include both religious and spiritual works, concepts and applications.  No religious work can get you to God.  Jesus did the work of dying for your sins on the cross.  Religious people killed Him.  But the good news is that He rose again (in the flesh) on the third day by the Spirit of God because He had not sinned.  [John 1:17 KJV] For the law was given by Moses, [but] grace and truth came by Jesus Christ. [John 4:24 KJV] God [is] a Spirit: and they that worship him must worship [him] in spirit and in truth. 

The Spirit of God knows you better than you know yourself.  You can’t lie to God, either.  God knows if you want to give your life to Him, or live for yourself and your sins in this world. He certainly knows what you believe in your heart about His Son and if  you’ve accepted His payment for your sins, or not. That’s why God Himself will ‘validate’ your belief and personally send you His Spirit when He knows you have come into agreement with Him and believe in your heart that Jesus died for your sins and that He rose again. 

Until then, you are simply playing at religion or living for your old ways, but you will never fool God. 

[Luke 5:31-32 KJV] And Jesus answering said unto them, They that are whole need not a physician; but they that are sick.  I came not to call the righteous, but sinners to repentance.

[John 3:7 KJV] Marvel not that I said unto thee, Ye must be born again.
