To have FAITH is to BELIEVE the word of GOD:
“[FOR SINCE THE BEGINNING OF THE WORLD MEN HAVE NOT HEARD, NOR PERCEIVED BY THE EAR, NEITHER HATH THE EYE SEEN, O GOD, BESIDE THEE, WHAT HE HATH PREPARED FOR HIM THAT WAITETH FOR HIM]” (Isaiah 64:4).
“Now [FAITH] is the substance of things hoped for, the evidence of things not seen” (Hebrews 11:1).
“By [FAITH] Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.
By [FAITH] he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise: For he looked for a city which hath foundations, whose builder and maker is God” (Hebrews 11:8-10).
“By [FAITH] Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God” (Hebrews 11:5).
“But [WITHOUT FAITH] it is [IMPOSSIBLE TO PLEASE HIM: FOR HE THAT COMETH TO GOD MUST BELIEVE THAT HE IS], and that [HE IS A REWARDER OF THEM THAT DILIGENTLY SEEK HIM]” (Hebrews 11:16).
“[NO MAN HATH SEEN GOD AT ANY TIME; THE ONLY BEGOTTEN SON], which is in the bosom of the Father, he hath declared him” (John 1:18).
“But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the [WORD OF FAITH], which we preach; [THAT IF THOU SHALT CONFESS WITH THY MOUTH THE LORD JESUS, AND SHALT BELIEVE IN THINE HEART THAT GOD HATH RAISED HIM FROM THE DEAD, THOU SHALT BE SAVED]. For with the [HEART MAN BELIEVETH UNTO RIGHTEOUSNESS; AND WITH THE MOUTH CONFESSION IS MADE UNTO SALVATION]” (Romans 10:8-10).
“The LORD is [GOOD UNTO THEM THAT WAIT FOR HIM, TO THE SOUL THAT SEEKETH HIM]. It is [GOOD THAT A MAN SHOULD BOTH HOPE AND QUIETLY WAIT FOR THE SALVATION] of the LORD” (Lamentations 3:25-26).
However, our Lord Jesus has warned saying: “Nevertheless when the Son of man cometh, shall he find faith on the earth? (Luke 18:8).
