I got married long time ago, and I have a daughter. I love my

wife and daughter more and more after I became a Christian. Also I understand them better than before. I have more patient and love for them.
Everyone said I was a very nice man, family members, friends, prefessors, co-workers, even strangers in most case. But before I became a Christian, I knew I have no real peace in my heart, and I was always looking for it.
I was practicing Daoisam and Buddisam before teenage. I have seen great masters who can do really great things or say super-nature things which can't be explained by current sciences.
But why they can do it? How peaceful are they? Are these achievements or ability is realy what they are dreaming for?
What will happen after their fresh? Where is the Wisdom coming from? Where is the source? What's the relationship between our thinking, our live with the wisdom source? On and on, I can't find the answers, even no clue about my direction.
But thanks God. God always has His way to direct people. I become a believer without suffer any pain.
