If you really have a love of truth, and genuinely intend to honour God with reverence,
you have to be prepared to humbly acknowledge Him and repent of excluding Him
from your life and value system. If you are being true and sincere, God will grant to
you a measure of faith by a Spiritual work in you, by which you will WANT to know
the Gospel ~ that Jesus died and shed His blood to redeem you from sin and death.
If you really value the truth, God will draw you to Him by that work of the Spirit, and
you will receive the proof that He is real - in a way that is personal evidence for you.
Nobody can sit as a judge or critic, expecting Almighty God to put on a "command
performance" to satisfy some arrogant whim. He knows if your motives are "real", or
if it is only an exercise in arrogance.
