A man who is grateful to God acknowledges God as his source. He realises that whatever he is or achieves comes from the help of God and the resources God has made available.
We must have this sense of dependence on God always and one of the best ways we show and express that dependence is to express heartfelt gratitude to God for all his many blessings.
Gratitude is therefore the voice of trust and dependence.
But before we jump on the thanksgiving bandwagon, we need to realize that genuine thankfulness is inextricably bound up with trust. We will never truly thank God until we first truly trust Him. We will not be grateful to God for all that we have until we first recognize that we’re dependent on Him for all that we have.
When God commands us to give thanks, not only is he instructing us to do what is right; he is at the same time directing our attention away from things that are draining our hope and fueling our discouragement, to what will fill us with hope and fuel our courage. The commands are themselves graces.
