Agnostic / atheist Bertrand Russell wrote a clear description of the atheist worldview:
That Man is the product of causes which had no prevision of the end they were achieving, that his origin, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collections of atoms, that no fire, no heroism, no intensity of thought and feeling, can preserve an individual life beyond the grave, that all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man’s achievement must inevitably be buried beneath the debris of a universe in ruins–all these things, if not quite beyond dispute, are yet so nearly certain, that no philosophy which rejects them can hope to stand. Only within the scaffolding of these truths, only on the firm foundation of unyielding despair, can the soul’s habitation henceforth be safely built. (Bertrand Russell, Mysticism and Logic (New York: Barnes & Noble, 1917), p.47-48)
By contrast, God speaks to us through the apostle Paul:
For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord. (Romans 8:38-39).
We could go on to quote many atheists who state clearly that we all live a purposeless lfie, upon a purposeless planet, doomed to a purposeless end. We can also go on to quote passages where God tells us that love truly exists, that He has a plan and a purpose for us and for His creation, and that goodness does indeed exist. The place to put our trust is clear: in the Lord God of the universe. Do we build on a foundation of unyielding despair, or do we build upon the firm rock of Jesus Christ? The choice is yours.
