When someone thanks you or appreciate something you’ve done for them it makes you more willing to help a person like that why? Because it makes you feel appreciated right? When someone does something for you or has done something for you it’s important for you as well to be thankful and appreciative.
It’s even more important to give God thanks for all that he’s done for you. Jesus himself demonstrated this for us to see. Before Jesus fed the five thousand or the four thousand the first thing he did before he broke the bread was give thanks. It was after Jesus gave thanks and broke the bread ( breaking it in faith believing God would provide) then God the father multiplied (increased) the food and provided just what they needed to be satisfied. Jesus didn’t give thanks to receive something from God he gave thanks from a sincere heart and the father provided on both occasions.
41 Taking the five loaves and the two fish and looking up to heaven, he gave thanks and broke the loaves. Then he gave them to his disciples to distribute to the people. He also divided the two fish among them all. 42 They all ate and were satisfied, 43 and the disciples picked up twelve basketfuls of broken pieces of bread and fish. 44 The number of the men who had eaten was five thousand.
6 He told the crowd to sit down on the ground. When he had taken the seven loaves and given thanks, he broke them and gave them to his disciples to distribute to the people, and they did so. 7 They had a few small fish as well; he gave thanks for them also and told the disciples to distribute them. 8 The people ate and were satisfied. Afterward the disciples picked up seven basketfuls of broken pieces that were left over. 9 About four thousand were present.
Like Jesus we should give thanks out of a sincere heart not looking for something in return.
1 Chronicles 29:13
13 Now, our God, we give you thanks, and praise your glorious name.
