As a Believer in God and Jesus Christ, I know I am empty without God in my life. I know I would be lost without Him and would have no sense of right and wrong or desire to do right. To piggyback off what JagBR said, I too can never get enough of His Word; the more I study His Word and attend Bible study, the more I am amazed by Him and His love for me. I will never be too complacent in my relationship with Him but will always want to go higher in Him.
I'm 41 years old (not quite young but not too old) and when I think of my life and all the bad choices/decisions I've made, when I think of all those times I put myself in situations that I knew weren't good for me, when I think of how things could have gone the other way in my life, when I think how so much has happened to me that I should be crazy, and about those things that should have taken me out of this world............I know it was nothing but the Grace of God that kept me, kept my mind, kept me from harm, kept me at peace, and He is still keeping me. God is so wonderful, so amazing, so strong, so mighty, so very awesome to me; I love how He loves me and wants the best for me and my household; I love how he sent me Salvation and Redemption through His Son. I love how He has been better to me than I've been to myself. And love how He loves me enough to leave me His instructions and Word on how to live my life for Him so that I may one day be with Him.
I am nothing without Him; He is my way in, my way out, my way over, my way through; He is my hope, my strength, my joy, my refuge.......I include Him in everything because He is my everything.
