Once you know the Lord and felt his presence, you will know eventually that you can't escape from his love. From time to time there will be trials that you will fail to overcome and at some point of your life you will find your self doing things that you once hated and thought you'd never do because you wanted to be free, free to do whatever you want. But through those struggles, there will always be someone who'll guide you back, and at that point, your faith in Him will become stronger.
