To give thanksgiving unto God we must recognize His hand in our lives. What blessings has He given to you? A great idea is to get out a piece of paper (or open a new document) and number your blessings one by one.
As you count your blessings, be specific. Name individual family members and friends. Think of your life, health, home, city, and country. Ask yourself what, exactly, about your home or country is a blessing? How about your skills, talents, education, and job? Think about those times that seemed like a coincidence; did you overlook God's hand in your life? Did you think of God's greatest gift, His Son, Jesus Christ?
You will be amazed at how many blessings you truly have. Now you can show thanksgiving to God for them.
