What does Mark 8:6 mean?

"Thanks" is from the Greek root word eucharisteo and means to be grateful or give thanks. It is the word from which we get "Eucharist," also known as communion or the Lord's supper. As Jesus gives thanks to God for providing food for the crowd, we are reminded of the many things we should be thankful for.

Our own meals: God knows that we need food before we do, and He will provide what we need to accomplish His work. That may not include gourmet dinners, or even three square meals a day, but it will be what we need in the moment.

God's work in our lives: Just as God's power made seven loaves enough to feed four thousand men plus women and children, God works in our lives every day. Sometimes we notice and sometimes we don't. He is there when we have just enough money to cover an unexpected expense. Or when we're exhausted but find the energy to be what our kids need. Or when a friend provides encouragement right when we need it. "The steadfast love of the LORD never ceases; his mercies never come to an end" (Lamentations 3:22).

God's invitation to join His work: The Trinity is three Persons in complete community. When God made us in His image, He gave us a taste of that union in our need for each other. Although the Holy Spirit indwells each believer individually, He also leads us to care for each other (3 John 1:5–8), confront each other (Matthew 18:15–20), and show God's love to each other (1 John 4:7–21). As Jesus breaks the bread, the disciples pass it out. Perhaps they think they are Jesus' important representatives, acting under His authority—and they are. But they will learn that their position is also as the "servant of all" (Mark 9:35).
