I can't really think of a time when God's divine providence hasn't been in my life, even before I knew anything. I have always inherently known that Jesus is the Son of God, that he lived, died and was resurrected, even though I was never taught that. In fact, I was taught to believe that it wasn't true, but in my heart and soul, I always knew it was without any explanation as to why or how I knew it. Everything else has sprung from my tenacious grip on that truth.
God has spared me from a lifetime of miseries that have befallen my siblings and parents. He has saved my very life more than a few times, He has given me an instinct or a grace to know the truth. I don't know why He did, because I know that I have never done anything to deserve any graces, but He gave them to me anyway.
