There has never been a shortage of ideas as to how mankind would fill the aching void within. Indeed, that is why we have so many philosophies and religions and ideologies. We search, and we don't know what we are searching for, and we search in all the wrong places. The Bible sums up the utter futility ...

"There is a way which seemeth right unto a man, but the end thereof are the ways of death." Proverbs 14:12

Our mindset has "changed the glory of the uncorruptible God into an image made like to corruptible man". (Romans 1:23) Consequently, "Professing ... to be wise, [we] became fools." (Romans 1:22)

We have sought to substitute the standards God requires with our own self-styled righteousness. Eternal death is the outcome of our efforts.
