Some children are grateful and full of joy when they receive the gift of a toy, while some others grumble because it is not what they wanted. Any of you would be pleased by the children who are grateful and you may even want to give them more. It is the same between God the Creator and human beings. When we realize God's grace and give thanks to Him in everything, God is pleased with us and blesses us greatly.
"Oh give thanks to the LORD, for He is good, for His lovingkindness is everlasting." (Psalm 107:1)
