Under Gods Command (Book of Leviticus)
Leviticus 7:28-30
28The LORD said to Moses, 29“Say to the Israelites: ‘Anyone who brings a fellowship offering to the LORD is to bring part of it as their sacrifice to the LORD. 30With their own hands they are to present the food offering to the LORD; they are to bring the fat, together with the breast, and wave the breast before the LORD as a wave offering.
God told the people of Israel to bring their fellowship offerings personally, with their own hands. They were to take time and effort to express thanks to God. You are the best person to express your thankfulness to God and to others.
Lets Bring it Home: Do you leave it to others to express thanks to someone who has been helpful? Do you rely on the one leading in prayer to thank God for you? Take time to communicate your personal gratitude both to God and to others who have helped and blessed you.
