Believe is only half the Equation

Believe is only half the Equation

You believe that God is one. You do well; the demons also believe, and shudder. James 2:19 (NASB)

Throughout the years of my life and even now, I still hear many Christians
when witnessing to non-Christians say the following; “you just have to
believe”. Or just in general conversation will say “ I believe this…” or “I
believe that…” Believe in what? Is usually the question in the back of my
head. What does it mean to believe? More importantly, as a Christian what
does it mean to believe in Jesus? Jesus said in John 14:6
“I am the way, and the truth, and the life; no one comes to the Father but through Me. One definition of truth as defined by Merriam Webster dictionary is “of being in accord with fact or reality”. So what does truth and belief have to do with one another you may be asking? If belief is not grounded in truth then it is a myth which by Merriam Webster is defined as “an unfounded or false notion”. Consider this;
I “believe” that I can fly, and that if I climb to the top of the Empire State building and leap of the observation deck, that I’ll be able to fly over Manhattan like a bird. The reality, the “truth” is when you leave the building and spread your arms out to fly, gravitation/gravity, which is always present (truth), rears its head, and you now have a date with a sidewalk 1,250 feet (102 stories) below. It is not enough just to believe in something or someone, it must also be grounded in the truth (being in accord with fact or reality) of what that something or someone is or else it is a myth (an unfounded or false notion). To simplify; truth is objective, belief is subjective. Jesus is truth because he was/ is real, He existed/exists. Why do I believe this? Because:
History bears Him out. Examples are
Flavius JJosephus- “Antiquity of the Jews”
Publius Tacitus- “Annals of Tacitus”
Letter to Pliny the Younger from Emperor Trajan
TheBible
My life has born Him out, changing me from the man I was, lost and without life to the man I have become, found and full of life. Hebrews 11:1 says “Now faith is the assurance of things hoped for, the conviction of things not seen.” My faith or my assurance is based on my belief; As it is written:

Romans 4:3
For what does the Scripture say? “Abraham believed God, and it was credited to him as righteousness.”
 
Galatians 3:6
Even so Abraham believed God, and it was reckoned to him as righteousness.
 
James 2:23
and the Scripture was fulfilled which says, “And Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God.
 
My belief is rooted in truth. Who is the truth? It is Jesus the Christ Himself (John 14:6).
