While many people know about God, fewer people know God personally unless they take time to be with Him on a daily basis. Do you desire to be heard by God? Do you desire to hear God? Do you desire to see things through His eyes? There is no short cut, no app, no pill for this. The only means is through daily prayers and devotional time.
For the year of 2019 I would like to strongly recommend Oswald Chambers Book “My Utmost for His Highest”. This classic devotional book has been one of the most renowned for over 80 years. Many readers are committed to reading it year after year because of its timeless truth and layers of challenges to go deeper. It will renew, revitalize, and energize you! In 2008 Pastor Floyd & Cindy Sollenberger gave this book to me, and I have been reading it ever since and even though it is the same devotion, it takes me closer to God.
