We used to sing this, and other hymns, in school–in our neighborhood public school. We Gather Together was always sung to celebrate Thanksgiving. It made for a better world. Humbly seeking God and giving thanks to Him always makes a better world. It’s when we seek after man that things start to fall apart.
But God is nigh, always nigh, He does not forget His promises, He hears us when we pray–and that is ample reason to give thanks.
