It is the greatest thing in the world to be a Born Again Christian. It's not just about being sure of Heaven either. All of a suddenly your life goes on cruise control with God showing you the way. The key is learning to accept that fact and respond when the Lord leads you in a certain direction. It took me a while after I was saved to understand that. Actually, about five years.
I always thought about God and sometimes prayed to Him even before I was saved. That didn't make me a Christian, but it kept from me being involved with smoking, alcohol and drugs. I had respect for God and fear of him. And you know what the Bible says, "The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction."
Sometimes things happened that I didn't understand. Later, I realized they were so that I would get saved, then grow spiritually and share God's Gift of Salvation with others. I like to share personal experiences in my books, rather than just quoting Bible verses, to make my point. When people do read the verses and how I apply them to various subjects, I believe it helps them to better understand how God works in our lives.
