The greatest threat to Christianity is never vigorous intellectual criticism but a creeping senility that transform truths into feelings, public claims into private experiences, and facts into mere values. Christianity is either true or false, ut it is not irrational. If its claims are not objectively true, then they are not subjectively useful. If our only reason for believing Jesus is alive is that “he lives within my heart,” then, as Paul said, “our preaching is in vain and your faith in in vain.” “We are even found to be misrepresenting God because we testified about God that he raised Christ…And if Christ has not been raised, your faith is futile and you are still in your sins…. If in Christ we have hope in this life only, we are of all people most to be pitied” (I Corinthians 15:14-19). We must recover our distinctively biblical commitment to rigorous, inquisitive, and persuasive thinking before there can be a genuine renewal of Christian conviction, faith, repentance and discipleship. It is time once again to love God with our minds.
