Can you explain the Kingdom of God, the Holy Spirit, and the reason for your faith, to someone who does not...

Of course I can explain it because I strongly believed in God. I will try my best to clearly explain by details what I knew is right and true eventhough he/she will not be convinced to believe me. If you trully believe on something, you can confidently tell something about it even if others won't believe you. The most important thing is you know how to defend yourself on what you believe in.
