The New Testament was originally written in Greek. The word believe comes from the Greek word pisteuo, which means to trust and the root Greek word of pisteuo is peitho which means to obey due to persuasion.
The gospel of John
We are going to look at three passages of scripture from the gospel of John, each verse requires faith.
John 3v16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 7v38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. 39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
John 14v12 Verily, verily, I say unto you, He that believeth on me, the *works that I do shall he do also; and greater *works than these shall he do; because I go unto my Father.
*It should be pointed out at this stage that the works mentioned in Joh 14v12 are shown in John 9v1-7 and Matthew 11v2-6 as the miracles that Jesus performed, which he said, bear witness of who he is, John 10v25, 32, 37, 38.
Again, I point out that the requirement in each of these scripture is to believe in Jesus Christ.
If we accept that John 3v16 is applicable to the believer, then we must also accept that John 7v38-39 and John 14v12 are also applicable.
So we see, the person who believes in Jesus Christ will receive the Holy Spirit, John 7v38-39, will do the same works (miracles) that Jesus did, John 14v12 and will have everlasting life, John 3v16.
All three passages are from the same gospel and all require a person to believe. We cannot isolate one passage such as John 3v16 and disregard the other two.
