"In the morning, O Lord, You will hear my voice; In the morning I will order my prayer to You and eagerly watch." Psalm 5:3
Get in touch with the One who created the day - to begin your day by spending a few minutes alone with God each morning? Study God's Word and share with Him, through prayer, your heart and your concerns. It will help get you in the right frame of mind. You'll find your day will start and finish a whole lot better.
Even if you're a night owl, start your day, whatever time that may be, in the same way. Spend a few minutes alone with God in your "morning" and you'll also find that your life will be enriched and blessed as the day progresses. And it would be a good idea to end your day with Him, too!
