Only Christianity, of all the world’s religions, has produced a real interest in man. Christianity is not romantic; it is realistic. Christianity is realistic because it says that if there is no truth, there is also no hope; and there can be no truth if there is no adequate base. It is prepared to face the consequences of being proved false and say with The Apostle Paul: If you find the body of Christ, the discussion is finished; let us eat and drink, for tomorrow we die. (1) 

It leaves absolutely no room for a romantic answer. For example, in the realm of morals, Christianity does not look over this tired and burdened world and say that it is slightly flawed, a little chipped, but easily mended. Christianity is realistic and says the world is marked with evil and man is truly guilty all along the line. Christianity refuses to say that you can be hopeful for the future if you are basing your hope on evidence of change for the better in mankind. The Christian agrees with the people in genuine despair that the world must be looked at realistically, whether in the area of Being or in morals.   

Christianity is the only religion that has a God who God who put on human skin and lived a sinless life ‘so that’ He could serve as a substitutionary sacrifice to die a death that you and I deserve in order to make full payment for a penalty that we owed.  He paid our penalty.  His resurrection is our ‘proof of life’. (2) 

The bible says He did this because He loves us.  The God who is there is a personal God who loves us.  From beginning to end.  He is love.  We love because He is love. (3) 

(1)  (I Corinthians 15:12-19 ESV   12 Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then not even Christ has been raised. 14 And if Christ has not been raised, then our preaching is in vain and your faith is in vain. 15 We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised. 16 For if the dead are not raised, not even Christ has been raised. 17 And if Christ has not been raised, your faith is futile and you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished. 19 If in Christ we have hope[a] in this life only, we are of all people most to be pitied.) 

(2)  (John 3:16 ESV    ¹⁶ “For God so loved the world,^[a] that he gave his only Son, that whoever believes in him should not perish but have eternal life.) 

(3) (1 John 4:19 ESV   ¹⁹ We love because he first loved us.)
