"BELIEVE" IS ALWAYS PRESENT TENSE

John 3:14-18 - "And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:  that whosoever believeth in Him should not perish, but have eternal life.  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.  For God sent not His Son into the world to condemn the world; but that the world through Him might be saved.  He that believeth on Him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God."

John 11:25-27 - "Jesus said unto her, I am the resurrection, and the life: he that believeth in Me, though he were dead, yet shall he live:  and whosoever liveth and believeth in Me shall never die. Believest thou this?  She saith unto him, Yea, Lord: I believe that Thou art the Christ, the Son of God, which should come into the world."

Acts 10:39-43 - "And we are witnesses of all things which He did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree:  Him God raised up the third day, and showed Him openly; not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with Him after He rose from the dead.  And He commanded us to preach unto the people, and to testify that it is He which was ordained of God to be the Judge of quick and dead.  To Him give all the prophets witness, that through His name whosoever believeth in Him shall receive remission of sins."

Romans 3:20-26 - "Therefore by the deeds of the Law there shall no flesh be justified in His sight: for by the Law is the knowledge of sin.  But now the righteousness of God without the Law is manifested, being witnessed by the Law and the Prophets; even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:  for all have sinned, and come short of the glory of God; being justified freely by His grace through the redemption that is in Christ Jesus:  Whom God hath set forth to be a propitiation through faith in His blood, to declare His righteousness for the remission of sins that are past, through the forbearance of God; to declare, I say, at this time His righteousness: that He might be just, and the justifier of him which believeth in Jesus."
