Given the context of a discussion forum it appears to be an invitation to discuss the premise:
The above statement is logical, valid premise and fundamentally correct from a scriptural perspective. This is evidently reflected by the apostle Paul’s statement at 1 Corinthians 15:19:
“If in this life only we have hoped in Christ, we are of all men most to be pitied” (1 Corinthians 15:19)
Moreover, what applies to a resurrection promise applied to the existence of God and His revealed purpose, if one is true the other is also.
The axiom is interesting because as the existence of life denotes a life giver, so does the ability to reflect and reason provide ample evidence of a designer of the innate mental processes.
However belief in the existence in a creator is not sufficient as stated by James: “ You believe there is one God do you? You are doing quite well. And yet the demons believe and shudder.” (James 2:19)
What is worthwhile in addition to belief based on such sound reasoning is accurate knowledge of God’s requirements.
Two sources of such knowledge are reflectively contemplating God’s creation and prayerfully examining His revealed inspired words.
Psalm 19:1-9 “The heavens are declaring the glory of God...”; and “the law of Jehovah is perfect...”
In complete contrast with human reasoning the bible encourages seeking ‘accurate knowledge for salvation’ and contemplating “things written aforetime for our instruction” that we might have guidance comfort and hope” directly from the living God.
