Doubt is a feeling of uncertainty, disbelief or distrust. A doubtful man has doubt by an action forced by a built-in state of thought which may lead to an abuse as a substitute. Doubts are difficulties when men do not understand and can lead to absorb arguments. The words probable or possible are shadows of doubt.
Belief is an action forced to resist doubt entirely by holding an opposite state of mind in rules for that situation. Two moments of truth can't break one doubt because of uneasy suspicion.
Doubt diversifies faith to gain the unbelief. There is no faith lives in honest doubt. A man can be so near to God yet one doubt can strike it out. One useful belief is better than thousands of doubts and thousands of difficulties should not make one doubt. There is no sunnier side to a doubtful man, for nothing is worthy of proving can be proven.
Doubt is an attempt to seduce the man to hell. Doubt cuts off a piece of the picture preventing its preservation for its chief treasure, example: the Da-Vinci Code; the Quran because the truth do not dwell upon them.
Men needs to stand upon the truth or shall shrink to a little measure as doubt has no happy ending. Doubt is the devil advocate urging the case by argument against. A doubtful man calls the chess-board white when it is black. Doubt is a kind of warfare begins in the soul by the adversary to be organized in group of ideas, principles, philosophy and beliefs forming a formidable opposition in the brains. Doubt erode our confidence and defeat hope. It arises because we look at the problem instead of God who is unlimited in abilities. We are not created to be doubtful. The Grace of God upon us has no doubt but comes when we are without doubt. God is love and love has no doubt.
God put good and evil in the word “doubt” so every able-bodied of man and woman are capable of digging their own allotment in their spare time for their own victory.
Examples: the truth’s certainty begins with doubt. When you are in doubt you can think and strike the big answers.
Doubt in science is necessary for proving a hypothesis and sparks further creativity. Reasons convince us with what we believe even if might not be true. For example believing in adventure is more fatal to health than taking care. Adventure has the most terrifying experiences but we like it for the wrong reason. There are reasons that kill reasons and there is passion that conquers reason. The truth to be reached requires facts and reasons, this is why we need the reason to know the why.
In an uncertain and changeable world, we need to stand for educational revolution. Book reading restores a full man; books are where things are explained while life where things aren't. A linger not allowing new things to happen that might change the course of your life. The discovery of what else you might do can make life completely different, towards the better.
The truth is the only thing you can sink your teeth in; Doubt the truth and be a liar. Our worthiness, prevail us as God's precious children. If a thing is worth doing badly, we should do it. The worth of the state in the long run, is the worth of the individuals composing it.
When St. Peter was walking on water, his confidence was overcomes by doubt. Peter focused on the gravity problem instead of Jesus. He was allowed to drawn then Jesus saved him. The challenge changed into victory when he started to focus on Jesus. Peter walked on the water by faith in Jesus who stands for the absolute truth. Thus the lessons learned are: doubt bar the door against miraculous answer to be beaten by the devil, "be doubtful and sink". Also doubt can be a starting place for a double thinking to unite with God.
Thomas found it hard to accept that Jesus was really resurrected. Jesus said to him put your finger on the hole in my hand and my feet where I was nailed and quit being faithless. Touch me and make sure I am not a ghost because ghost don't have bodies. Jesus then said: "blessed those who believed and not yet seen". Jesus then ate a piece of boiled fish with the disciples.
The truth of Jesus claims was validated by His Resurrection seen by countless credible witnesses. The Disciples were transformed from cringing cowards to courageous witnesses who could not be silenced free from fear.
Thomas is one of the twelve, notorious for his doubts and depression (John 14, 5:20,24). But when Jesus decided to go to Bethany when Lazarus was ill, the rest of the disciples tried to dissuade Him, it was Thomas who said "let us go and die with Him" (John 11, 16). He later became a missionary to the East Parthia and Persia and is said to have died in India near Madras.
