His answer gets personal when he talks about a time he tried to take his own life--that was prior to his coming to know Jesus as His personal Savior and Lord.
I invite you to stop, Click Here on this hyperlink to hear this great Christian apologist deal with this important issue.
May I suggest that you consider having a piece of paper or notebook and pen ready to take notes on what Dr. Ravi Zacharias has to say on this subject. He clearly defines the value of a human life. He reminds us that God is Sovereign and man is responsible to God. Each one of us will give an account to God for the sacred trust He has given to us in life. He concludes his answer with one of my favorite poems that was quoted by King George VI in his 1939 Christmas broadcast to the British Empire:
And I said to the man who stood at the gate of the year:
“Give me a light that I may tread safely into the unknown.”
And he replied:
“Go out into the darkness and put your hand into the Hand of God.
That shall be to you better than light and safer than a known way.”
So I went forth, and finding the Hand of God, trod gladly into the night.
And He led me towards the hills and the breaking of day in the lone East.
